Constructive Interference Precoding for Generalized Precoding-Aided Quadrature Spatial Modulation With Phase-Shift-Keying Signaling

In this letter, we formulate computationally efficient precoder and detector design problems for symbol-level generalized precoding-aided spatial modulation (GPQSM) systems with phase-shift-keying signaling. We first present a novel low-complexity decoupled detector. Subsequently, we formulate two new precoders using constructive interference (CI) techniques to enhance the performance of the propo...
