Space-time coding (STC) schemes for Multiple Input Multiple Output (MIMO) systems have been an area of active research in the past decade. In this thesis, we propose a novel design of Space-Time Block Codes (STBCs) using Redundant Residue Number System (RRNS) codes, which are ideal for high data rate communication systems. Application of RRNS as a concatenated STC scheme to a MIMO wireless communication system is the main motivation for this work. We have optimized the link between residues and complex constellations by incorporating the “Direct Mapping” scheme, where residues are mapped directly to Gray coded constellations. Knowledge of apriori probabilities of residues is utilized to implement a probability based “Distance-Aware Direct Mapping” (DA) scheme, which uses a set-partitioning approach to map the most probable residues such that they are separated by the maximum possible distance. We have proposed an “Indirect Mapping” scheme, where we convert the residues back to bits before mapping them. We have also proposed an adaptive demapping scheme which utilizes the RRNS code structure to reduce the ML decoding complexity and improve the error performance. We quantify the upper bounds on codeword and bit error probabilities of both Systematic and Non-systematic RRNS-STBC and characterize the achievable coding and diversity gains assuming maximum likelihood decoding (MLD). Simulation results demonstrate that the DA Mapping scheme provides performance gain relative to a Gray coded direct mapping scheme. We show that Systematic RRNS-STBC codes provide superior performance compared to Nonsystematic RRNS-STBC, for the same code parameters, owing to more efficient binary to residue mapping. When compared to other concatenated STBC and Orthogonal STBC (OSTBC) schemes, the proposed system gives better performance at low SNRs.

Full textSpace-time Coding (STC) for Multiple-Input Multiple-Output (MIMO) wireless communication systems is an effective technique for providing robust wireless link performance in telemetry systems. This paper investigates the degradation in system performance when synchronization errors between the transmitter and receiver are present. Specifically, expressions that quantify the increase in symbol-error-rate as a function of symbol synchronization error are derived for a two-transmit and single receive antenna MISO system using binary frequency shift keying waveforms. These results are then extended to the MIMO case. The analytic results are verified with simulation results that show close agreement between the theoretical expressions and Monte Carlo simulation runs.

Space time block codes (STBC) are a type of multiple input multiple output (MIMO) communications system that encode blocks of information into symbol sequences sent simultaneously from multiple antennas. MIMO communications systems have shown channel capacity improvement in multipath digital communications environments. The STBC class of MIMO communications systems can be easily decoded using linear combination and is resilient in the face of multipath channel effects. MIMO systems have traditionally been studied using theoretical analyses, simulations and real signal based experiments. Probabilistic models simulate channel effects as random variables, but are only estimates of actual conditions. Real signal experiments evaluate system performance under real-world conditions, but are not readily repeatable. Both modeling methods evaluate system performance in terms of the aggregate results. This dissertation research presents an approach that introduces controlled attenuation and delay to probabilistic channel models. This method allows the evaluation of MIMO system performance under specific channel conditions. The approach is demonstrated with a hardware accelerated STBC system model that is used to evaluate the performance of a MIMO system under controlled path conditions. The STBC system model utilizes a Xilinix® programmable gate array (PGA) device as a hardware accelerator. The model exploits the parallel processing capability of the PGA to simulate a nine path channel model and a three antenna rate ½ STBC. Novel implementations are developed for the additive white Gaussian noise (AWGN) sources and the linear MIMO decoding in PGA hardware. The model allows specification of overall noise and multipath fading effects for the channel as well as attenuation and phase delay for each channel path. Performance of the communications system is evaluated in terms of bit error rate (BER) versus signal-to-noise ratio (SNR). Hardware acceleration greatly reduces the time required to obtain simulation results. Reduced simulation time improves the use of the model by allowing evaluation of system performance under a greater number of conditions, greater performance curve resolution and evaluation at lower BER. The processing rate of the hardware accelerated model is compared to an equivalent software model. The model also provides an extensible platform for future research in communications theory.

A numerical example for a frequency flat time correlated channel is given to show the impact of channel estimation.

Full textBoth techniques provide a means for combatting the effects of multipath fading without adding much complexity to the receiver. This is especially useful in the downlink of wireless systems. In this thesis we investigate the impact of channel estimation error on the performance of both STBC and STTC.
Channel estimation is especially important to consider in multiple antenna systems since (A) for coherent systems there are more channels to estimate due to multiple antennas and (B) the decoupling of data streams relies on correct channel estimation. The latter effect is due to the intentional cross-talk introduced into STBC.

Full textThe latest wireless communication techniques such as highspeed wireless internet application demand higher data rates and better quality of service (QoS). However, transmission reliability is still degraded by harsh propagation channels. Multiple-input multiple-output (MIMO) systems can increase the system capacity and improve transmission reliability. By transmitting multiple copies of data, a MIMO system can effectively combat the effects of fading. Due to the high hardware cost of a MIMO system, antenna selection techniques have been applied in MIMO system design to reduce the system complexity and cost. The Nakagami-m distribution has been considered for MIMO channel modeling since a wide range of fading channels, from severe to moderate, can be modeled by using Nakagami-m distribution. The Rayleigh distribution is a special case of the Nakagami-m distribution. In this thesis, we analyze the error performance of two MIMO schemes: maximal-ratio combining with transmit antenna selection (the TAS/MRC scheme) and space-time block codes with transmit antenna selection (the TAS/STBC scheme) over Nakagami-m fading channels. In the TAS/MRC scheme, one of multiple transmit antennas, which maximizes the total received signal-to-noise ratio (SNR), is selected for uncoded data transmission. First we use a moment generating function based (MGF-based) approach to derive the bit error rate (BER) expressions for binary phase shift keying (BPSK), the symbol error rate (SER) expressions for M-ray phase shift keying (MPSK) and M-ray quadrature amplitude modulation (MQAM) of the TAS/MRC scheme over Nakagami-m fading channels with arbitrary and integer fading parameters m. The asymptotic performance is also investigated. It is revealed that the asymptotic diversity order is equal to the product of the Nakagami fading parameter m, the number of transmit antenna Lt and the number of receive antenna Lr as if all transmit antenna were used. Then a Gaussian Q-functions approach is used to investigate the error performance of the TAS/STBC scheme over Nakagami-m fading channels. In the TAS/STBC scheme, two transmit antennas, which maximize the output SNR, are selected for transmission. The exact and asymptotic BER expressions for BPSK are obtained for the TAS/STBC schemes with three and four transmit antennas. It is shown that the TAS/STBC scheme can provide a full diversity order of mLtLr.

Full textFree-space optical (FSO) communication has been the subject of ongoing research activities and commercial attention in the past few years. Such attention is driven by the promise of high data rate, license-free operation, and cheap and ecological friendly means of communications alternative to congested radio frequency communications. In most previous work considering multiple transmitters, uncorrelated channel conditions have been considered. An uncorrelated channel requires sufficient spacing between transmitters. However, this can be difficult and may not be always feasible in some applications. Thereby, this thesis studies repetition codes (RCs) and orthogonal space-time block codes performance in correlated log-normal FSO channels using intensity modulation and direct detection (IM/DD). Furthermore, the effect of different weather conditions on the average bit error rate (ABER) performance of the FSO links is studied. Multiple-input multiple-output (MIMO) FSO communication systems using space shift keying (SSK) modulation have been also analyzed. Obtained results show that SSK is a potential technique for spectral efficiencies equal or greater than 4 bits/s/Hz as compared to RCs with multiple pulse amplitude modulations. The performance analysis of a multi-hop decode and forward relays for FSO communication system using IM/DD is also considered in this thesis. It is shown that multi-hop is an efficient technique to mitigate atmospheric turbulence and different weather attenuation effects and geometric losses in FSO communication systems. Our simulation results show that multiple-input single-output (MISO) multi-hop FSO systems are superior to direct link and MISO systems over links exhibiting high attenuation. Meeting the growing demand for higher data rates communication networks, a system with full-duplex (FD) relays is considered. For such a system, the outage probability and the ABER performance are analyzed under different turbulence conditions, misalignment error and path loss effects. FD relays are compared with the direct link and half-duplex relays. Obtained results show that FD relays have the lowest ABER and the outage probability as compared to the two other systems. Finally, the obtained results in this thesis are very promising towards the next generation of FSO systems

The multipath wireless channel suffers severe attenuation. The effective techniques to mitigate multipath fading are time and frequency diversity. In most situations, the wireless channel is slow varying and frequency non-selective. Hence, antenna diversity is a practical technique for reducing the effect of multipath fading. Multiple input multiple output wireless channels can introduce spatial diversity and increased information capacity. These results have motivated a new area in error correcting codes. Space-time codeing(STC) schemes combine the channel code design and the use of multiple transmit antennas. With combining Multi-level coding technique and set partition of space-time block code set, We will propose a novel design of space-time block codes. Using Multi-level coding technique can get lower complexity and the better performance.

Abstract The multipath wireless channel suffers severe attenuation. The Effective techniques to mitigate multipath fading are time and frequency diversity. Foschini,Gans and Telatar proved that multiple input multiple output can introduce spatial diversity and increased information capacity. These results have motivated a new area in error correcting codes . Space-Time Coding (STC) schemes can combine the channel code design and the use of multiple transmit antennas . The Space Time Trellis Codes (STTC) proposed by Tarkoh combine the trellis coding with symbol mapping into multiple transmit antennas . The Coding scheme expansion is done in antenna space. The Turbo Codes proposed by Berrou have powerful error correcting abilities. It would be benefit to design turbo codes for multiple antenna systems. To design space-time turbo codes with maximum space diversity and outstanding performance is still an open question. The Turbo Codes exhibited a troublesome error floor. Besides, the MAP algorithm which performs maximum likelihood bit estimation has a very large computation complexity . Recently turbo product codes (TPC) have been proposed . It can proved the performance of turbo codes. It is expected that TPC for multiple antenna systems would be powerful coding schemes with maximum diversity gain and large coding gain.

Space-time coding and modulation exploit the presence of multiple transmit antennas to improve the performance on multipath radio channels. Various space-time coding schemes have been proposed. However so far, most research on space-time coding has assumed that perfect estimates of current channel fading conditions are available at the receiver. However, in certain situations, we may want to forego channel estimation in order to reduce the complexity and cost of the handset, or perhaps fading conditions change so rapidly that channel estimation is difficult or requires too many training symbols. The thesis presents several practical, feasible, and simple transmission schemes for exploiting diversity given by multiple transmit antennas when neither the transmitter nor the receiver has access to channel state information. The new detection scheme can use equal energy constellations and encoding is simple. At the receiver, decoding is achieved with low decoding complexity. The transmission requires no channel state side information at the receiver. The schemes can be considered as the extension of differential detection schemes to two transmit antennas.

In this thesis, we concentrate on the study of high-rate space-time block codes in the MIMO system. Multilevel coding scheme is adopted to improve the coding gain. Then, Reed-Solomon Codes are further concatenated to provide better error correcting capability. Computer simulation is performed to verify the error performance.

The wireless channel suffers severe attenuation caused by multipath fading. The effective technique to mitigate multipath fading is to use the time or frequency diversity. The communication system with multiple input multiple output can combat the channel attenuation by spatial diversity and increase the channel information capacity. The principle of space-time coding schemes is to combine the concept of channel coding design and multiple transmit antennas, which are then effectively applied to multipath wireless channel. Since the amount of data transfer of the modern digital or mobile communication is increasing, the reliability of the data transfer has become more and more important. Therefore, the error correction coding has played a very important role in wireless communication channel. The turbo code is one of the most popular error correction codes at present due to its good error correction ability. Besides, the turbo code is adopted in the 3G mobile communication standard. In this thesis, we present the application of several important concepts of wireless digital communications, i.e., serial concatenation, turbo coding, and temporal and antenna diversity . We combine the turbo code and the space-time block code and use the LogMAP algorithm to implement the soft in/soft out decoding algorithms of turbo code. Finally, we present our simulation results under different encoding scheme of the space time block code. Furthermore, we also present the comparison of the simulation result under different rate of space-time block codes but the same number of transmit antennas.

The multi-input-multi-output (MINO) technique is one in the breakthroughs of wireless communications. Space time block code (STBC) with maximal ratio receive combining (MRRC) is one of the systems using MIMO to reduce error rate by increasing the numbers of antennas in transmitter and receiver. The system performance can be greatly improved by applying error correcting coding, such as turbo codes and low density party check (LDPC) codes which are known because of performance approaching their to Shannon limits. In this thesis, we first introduce the traditional MRRC with 1 transmitter antenna and multi receiver antennas. Then we describe the property of STBC with multi transmitter antennas and multi receiver antennas. For error correcting codes, we use turbo codes and LDPC codes. In turbo codes, we use two parallel concatenated convolution codes for encoding and BCJR algorithm for decoding. For LDPC codes, we use IEEE 802.16e standard for encoding and sum-product algorithm for decoding. Finally, we combine turbo codes and LDPC codes with MIMO system and discuss the bandwidth efficiency of these combinations.

Space-time codes in both spatial and temporal domains have been proposed and become very popular for use in multi-input multi output systems. This thesis introduces a more general structure for super-orthogonal space-time codes called expanded super-orthogonal space time codes, which can retain the property that the maximum-likelihood decoding complexity is linear in the number of transmit antennas. Its codebook can be obtained by expanding the original space-time block code via both sides of unitary transformations. Besides, with a systematic parameterization, we can show a systematic procedure to obtain codebooks with optimal diversity gain. The results demonstrate better performance compared with super-orthogonal space-time block codes in terms of bit error rate.

Abstract In 2002, FCC decided to release 3.6~10.1 GHz spectrum for commercial use, and this indicates that future communication systems is of wideband and high transmission rate. However, for high data rate transmission the multipath channel results in time dispersive phenomenon and causes each symbol interfered by lots of symbols several time periods ago. For such intersymbol interference (ISI), or frequency-selective fading, the system needs complex time-domain equalization (TDE), for which the number of tap coefficients increases with the channel delay spread, and conventional time-domain equalization (TDE) may be of high complexity since the necessary number of tap coefficients increases with the channel delay spread. In this thesis, to avoid the complex time-domain equalization in the multipath channel, we first study the single-carrier block transmission with frequency-domain equalization (FDE). Similar to the orthogonal frequency-division multiplexing (OFDM) transmission, frequency-domain equalization has lower complexity than time-domain equalization. The SC block transmission also avoids the problem of high peak to average power ratio (PAPR) that occurs in OFDM transmission. We further consider SC block transmission with space time block coding (STBC), in which we study how to use permutation on the data sequences of the two antennas such that the receiver could have low-complexity data detection. Practical channel estimation based on a least square fitting (LSF) approach is also considered.

The space–time-block-code (STBC) multiple-input- multiple-output (MIMO) cyclic-prefix orthogonal frequency-division multiplexing (CP-OFDM) provides a good performance for the multiuser scenario. In this thesis, the channel impulse responses of the space- time-coded MIMO CP-OFDM system are shown to be identifiable up to two ambiguity matrices by subspace channel estimation. The time domain zero-forcing equalizer (ZF)) is used to detect OFDM symbols. Based on the Circular structure of channel matrix, We propose a novel approach to largely increase the number of OFDM symbols. The proposed subspace channel estimation can converge within a small amount of OFDM symbols.

In this thesis, we extend the fast ML detection algorithm to offer soft outputs such that near-optimum performance of the DSTBC is obtained. This extension is done by using the single-tree search (STS) technique which was developed for spatial multiplexing in multiple-input multiple-output communication systems. Simulation results show that the proposed soft-output algorithm outperforms the hard-output one approximately by 3 dB while its complexity is lower than the brute-force algorithm around 61.15%.

Foschini,Gans and Telatar proved that multiple input multiple output can introduce spatial diversity and increased information capacity. These results have motivated a new area in error correcting codes . The Space Time Block Codes (STBC) proposed by Tarkoh .Space-Time Coding (STC) schemes can combine the channel code design and the use of multiple transmit antennas . The Verilog language be Gateway Design Automation company build up since 1994 , Verilog language already become a standard hardware description language, Popularly use in VLSI and Digital System Design . Otherwise, Verilog language was first language can support any mix design level , At the same time provide Switch level、Logic level、Register Transfer Level and more than High-level describe. The Verilog simulation environment to provide a powerful combine environment to improve Digital Design step and test process. In our thesis, We will simply introduce Space Time Block Codes and Verilog HDL, we firstly use Matlab program to verify the correctness of our design ,After write Verilog HDL code to describe its function, Let the function can implement on chip.
