An Integrated Approach of ACM and CDMA in a Novel Multi User Spatial Modulation Scheme

The research focus in wireless communication access technologies is driven by the demand for high peak data rates and significantly improved spectral efficiencies, as well as the support for specific quality of service QoS requirements. By leveraging the orthogonality of space constellations and signal constellations, well established digital signal modulation schemes can be employed. The spatial multiplexing gain is achieved through the concurrent transmission of spatially encoded bits. This thesis investigates and compares the analytical and numerical performance of Spatial Modulation SM under various channel conditions, taking into account practical channel considerations, in comparison to existing MIMO techniques. The results demonstrate that SM achieves a low bit error ratio BER while substantially reducing receiver complexity, all while maintaining spectral efficiency.
