Quadrature spatial modulation (QSM) exploits the in-phase and quadrature antenna dimensions to increase the number of spatial constellation points. In this paper, an improved version of QSM, which is naturally called improved quadrature spatial modulation (IQSM), is proposed. The main feature of the proposed scheme is to send a second constellation symbol over the in-phase and quadrature antenna dimensions. A significant performance advantage of the proposed scheme is realized at the cost of a slight increase in the number of radio-frequency (RF) chains. Performance comparisons with the most recent spatial modulation schemes confirm the advantage of the proposed IQSM. A theoretical upper bound of the bit error rate is also given and shown to be very tight at high signal-to-noise ratios.
