Transmit antenna selection (TAS) is a practical method to improve the bit-error-rate (BER) performance of a multiple-input multiple-output (MIMO) systems. TAS is of particulate importance when spatial modulation (SM) is incorporated. Signed quadrature spatial modulation (SQSM) is a recently developed index modulation scheme that is based on the same concept of Quadrature Spatial Modulation (QSM) scheme. SQSM has superiority over QSM in term of spectral efficiency and BER performance with a moderate increase in receiver complexity. This paper studies the BER performance of low-complexity transmit antenna selection (LCTAS) on SQSM performance. Three different LCTAS techniques are applied to the SQSM and QSM schemes taking into consideration both the amplitude of the channel gains and correlations between antennas’ gains. The integration of LCTAS schemes with SQSM can significantly enhance the performance when compared to the conventional SM and QSM schemes.
