Abstract

In the Multi-user Generalized Spatial Modulation (MU-GSM) System, as channel gain matrix isn’t in full rank, conventional linear precoding algorithms can’t be directly applied in this system. Given this, a method called Multi-user Generalized Spatial Modulation Partial Linear Precoding (MU-GSM-PLP) is proposed for MU-GSM system. MU-GSM system is established in this method that the antennas at the transmitter are grouped and Generalized Spatial Modulation (GSM) is adopted in each antenna group. Then, dimensional reduction is made on channel gain matrix as well as transmitting signal matrix, and the equivalent channel gain matrix and transmitting signal matrix are obtained. Finally, Partial Linear Precoding (PLP) precoding is carried out by utilizing the equivalent channel gain matrix. The simulation results show that this method have a better error performance and higher system capacity.
