Abstract:

It thus reduces interchannel interference (ICI) and receiver complexity over traditional multi-antenna systems. However, the spectral efficiency of SM is low. To improve the spectral efficiency, generalized spatial modulation (GSM) can be used. In this paper, we propose to apply t

Abstract:
The present study analyses three beam shaping approaches with respect to a light-efficient generation of i) patterns and ii) multiple spots by means of a generic optical 4f-setup. 4f approaches share the property that due to the one-to-one relationship between output intensity and input phase, the need for time-consuming, iterative calculation can be avoided. The resulting low computational complexity offers a particular advantage compared to the widely used holographic principles and makes them potential candidates for real-time applications.

Abstract:
A novel energy efficient Multiple-Input-Multiple-Output (MIMO) technique is called Spatial Mod- ulation (SM). It uses only one radio frequency (RF) chain that reduces the hardware complexity and cost of the system. The concept of SM is to transmit the data information using modulation constellation and spatial constellation. It increases the spectral efficiency by keeping only one an- tenna active per every symbol period. Spatial Multiplexing (SMX) uses equal number of RF chains with transmit antennas that increases the hardware complexity and cost of the system. SM is free from Inter Ch

Abstract:
Considerando os avanços tecnológicos das últimas décadas, espera-se que a próxima geração de comunicações sem fios siga a tendência de um aumento significativo da robustez do sistema, da eficiência espectral (SE) e da eficiência energética (EE). Atualmente na era do pós-5G, os esquemas de "Multiple Input, Multiple Output" (MIMO) baseados em modulações espaciais generalizadas (GSM) bem como noutras modulações de índices (IM), têm sido amplamente considerados como potenciais técnicas candidatas para as redes sem fios.

In transmitter, the transmit antennas are divided into several groups and each group use GSM technique. Therefore, we don’t need a lot of Radio Frequency chain to transmit signal and will not cause serious inter-channel interference. Compare to the conventional GSM, we can implement high transmission rate system by using the characterist

Abstract:
Traditionally, symbols chosen from complex modulation alphabets such as QAM and PSK are used to convey information bits, and complex fades introduced by the channel are viewed as detrimental effects that cause amplitude and phase distortion to the transmitted symbols. An alternative and interesting approach is to consider the complex channel fade coefficients themselves to constitute a modulation alphabet (referred to as `channel alphabet'). An example of this approach is a recently proposed `media-based modulation (MBM)' scheme, which uses digitally controllable parasitic elements (called as

碩士<br>國立中山大學<br>通訊工程研究所<br>103<br>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)

The GSM systems activates only small number of transmit antennas at a symbol time which simply the complexity in implementation. Different selection of the activating antennas patterns change the average symbol error rate (SER) performance, however the optimal selection of the activating antenna patterns is an NP hard problem due to the complicated connection in the universe of antenna patterns set.
