A Reconfigurable SDR Transmitter Platform Architecture for Space Modulation MIMO Techniques

Space modulation is a group of multiple-input multiple-output (MIMO) techniques that attracted significant research interests lately. However, the aspect of implementation approaches and software defined radio (SDR) has been so far very limited. The aim of this paper is to propose a novel single SDR platform architecture that implements different space modulation techniques using currently available commercial off-the-shelf components. The proposed platform architecture can be dynamically reconfigured to implement different space modulation techniques with marginal to almost no extra hardware overhead. The impact of different hardware components that have to be considered to realize such an implementation is also analyzed and studied.
