Multi-set space-time shift-keying with reduced detection complexity

Multi-set space-time shift-keying with reduced detection complexity
Multi-set space-time shift-keying with reduced detection complexity
In this treatise, we propose a novel Multi-Set Space-Time Shift Keying (MS-STSK) technique, where the source bits are conveyed over two components, namely by activating one out of MQ dispersion matrices of Space-Time Shift Keying (STSK) and M Antenna Combination (AC) of the Nt available antennas, in a similar fashion to Spatial Modulation (SM) but activating multiple antennas rather than a single antenna. This system requires a smaller number of RF chains than Antenna Elements (AEs) to achieve an improved throughput. We opt for STSK as the main building block of our proposed MS-STSK as a benefit of its design flexibility, where STSK is capable of providing the system with both diversity and multiplexing gains. The proposed MS-STSK system achieves both higher data rates and a lower Bit Error Rate (BER) than the conventional STSK scheme, which is attained at the cost of increased number of antenna elements and a high-speed antenna switch. Furthermore, as the symbol rate of the MS-STSK system increases, its performance compared to the STSK scheme is significantly improved, because of the enhanced diversity introduced by the additional antenna elements. Furthermore, we propose a reduced complexity detector for QAM/PSK constellations, which - despite its reduced complexity - is capable of achieving the same performance as the optimal Maximum Likelihood (ML) detector.

Abstract

In this treatise, we propose a novel Multi-Set Space-Time Shift Keying (MS-STSK) technique, where the source bits are conveyed over two components, namely by activating one out of MQ dispersion matrices of Space-Time Shift Keying (STSK) and M Antenna Combination (AC) of the Nt available antennas, in a similar fashion to Spatial Modulation (SM) but activating multiple antennas rather than a single antenna. This system requires a smaller number of RF chains than Antenna Elements (AEs) to achieve an improved throughput. We opt for STSK as the main building block of our proposed MS-STSK as a benefit of its design flexibility, where STSK is capable of providing the system with both diversity and multiplexing gains. The proposed MS-STSK system achieves both higher data rates and a lower Bit Error Rate (BER) than the conventional STSK scheme, which is attained at the cost of increased number of antenna elements and a high-speed antenna switch. Furthermore, as the symbol rate of the MS-STSK system increases, its performance compared to the STSK scheme is significantly improved, because of the enhanced diversity introduced by the additional antenna elements. Furthermore, we propose a reduced complexity detector for QAM/PSK constellations, which - despite its reduced complexity - is capable of achieving the same performance as the optimal Maximum Likelihood (ML) detector.
