abstract

• Spatial modulation techniques (SMTs) are a promising solution for the design of future fifth generation (5G) and beyond communication systems, which activate only one or few antennas at the transmitter as per the incoming bit pattern. SMTs offer promising spectral efficiency, energy efficiency, and error performance with reduced hardware cost and complexity. Recently, fully quadrature spatial modulation (FQSM) has garnered attention as spectral efficiency SMT, which can vary the active antennas from one to multiple/all at any time instance. As more antenna subsets are utilized for bit mapping, spectral efficiency of FQSM grows linearly with the quantity of antennas at the transmitter. All SMTs suffer from huge error performance degradation under correlated channel conditions and hence in this paper, we evaluate the performance of FQSM under various channel fading scenarios. For performance evaluation, uncorrelated and correlated Rayleigh, as well as Rician channel fading scenarios are considered. Extensive Monte Carlo simulation demonstrates the superiority of the FQSM under various channel fading scenarios. © 2022 IEEE.
