Повний текст джерелаDirect spatial antenna modulation (DSAM) is a new approach to phased array control that opens up new "smart antenna" architecture possibilities. The DSAM technique leverages the inherent spatial differences of excitation in an antenna in a novel way to achieve the equivalent of conventional modulation and beam control effects. Smart antenna techniques are of potentially increasing importance to test range operations given a trend toward more flexible, internetworked, and autonomous test activities. The DSAM technique has been demonstrated through several generations of analysis, simulation, and prototyping, but has previously only been applied to narrowband antenna designs. Furthermore, the IQ DSAM approach in particular has not been previously implemented in hardware. This paper details the application of IQ DSAM to achieve wideband phase control using a commercial off the shelf (COTS) antenna. The phase control performance of IQ DSAM over a range of 1.5 GHz to 4 GHz is measured across relative field control angles of +/- 45 degrees. The measured IQ DSAM performance is compared to what could be expected from a conventional phased array element control architecture.

In the spatial modulation multiple input multiple output (SM-MIMO) system, the best detector is the maximum likelihood detector (MLD). But MLD has the problem of high computational complexity and is not easily implemented by hardware architecture. Therefore many detection algorithms that are of low computational complexity and error rate performance close to theMLD are studied. Extension of the conventional SM-MIMO system to use multiple active transmit antenna for transmitting different symbols is called multiple active-spatial modulation (MA-SM). Low complexity linear detection algorithm of MA-SM signals are comprised of two steps. In the first step, estimation of the L groups of active antennas is performed; and, detection of the transmit symbols from the estimated groups of active antennas is performed in the second step. Unlike the joint detection, such separate detection of the active antennas and transmit symbols is of low complexity at the expense of performance degradation. For the hardware implementation, a 4-by-4 MIMO system with two active antennas transmitting 16-QAM signals is considered. The number of groups L is set to 2. The fixed point simulation results suggest that word length of the proposed architecture is 13 bits. The proposed design is described by Verilog HDL and synthesized by Synoposis Design Compiler.

Spatial modulation in MIMO system (SM-MIMO) is a promising approach due to its low complexity and high energy efficiency properties. To enhance the SM-MIMO system performance, precoding at transmitter is shown to be effective. In this thesis, we investigate the precoder design techniques. With channel state information at transmitter, we propose two general precoder designs, including the problem formulations and its iterative algorithm, by manipulating the distance between codewords using optimization techniques. The designs can be virtually used in any type of SM-MIMO system. For practical concerns, codebook-based precoding is then introduced for SM-MIMO systems with limited feedback. To construct the effective codebook, we investigate the design criterion and propose three codebook design algorithms with different design considerations through exploiting the vector quantization techniques to maximize the average distance among codewords. Finally, the simulations show the effectiveness of the proposed designs in improving system performance, and confirm their superiority to existing works. Moreover, their feasibility in general SM-MIMO systems is verified as well. Furthermore, the proposed designs can indeed outperform other existing works.

The generalized spatial modulation (GSM) is developed as a promising modulation scheme which effectively compromises the hardware complexity and the spectral efficiency in the multiple-input and multiple-output (MIMO) systems. In this paper, we further propose a precoding design for improving the performance of GSM-MIMO systems. We first formulate precoding design as an optimization of which the worst-case minimum free-distance can be maximized. As well know, the free-distance is the critical metric in evaluating the performance of the maximum likelihood (ML) detection. To facilitate the derivation, we then decompose the precoder design into the power allocation times a structured precoder for each antenna group. With the decomposition, we can easily derive a closed-form solution for the precoder design, which can greatly reduce the computational complexity and is suitable for the real-time implementation. Simulation results show the superiority of our design measured by both the BER and computational complexity compared with the existing methods.

Orthogonal frequency division multiplexing (OFDM) is a multicarrier modulation technique. Since its high-speed transmission and robustness against frequency selective channel fading, it is widely adopted in modern wireless communications. However, high peak-to-average power ratio (PAPR) is disadvantage of OFDM. This leads to design problem of power amplifier. In the physical-layer of long Term Evolution (LTE), single-carrier is used for the uplink transmission, and this efficiently lessens the effect of high PAPR. In this thesis, we propose a frequency domain equalization technique for the single-carrier spatial modulation based multiple-input multiple-output system. We employ matrix inverse lemma for sub-block matrices to reduce the computational complexity of the involved matrix inverse in the minimum mean-squared error detection. Also, we apply the M-algorithm for use with the maximum-likelihood approach for selecting the candidates of decision. Results show that better error-rate performance can be obtained.
