Abstract

The features of Generalized Pre-coding aided Spatial Modulation（GPSM）are that in each time slot the bit information of space dimension is transmitted by selecting the active receiving antenna combination.In the same frequency spectrum efficiency and signal-to-noise ratio

GPSM shows better bit error performance when compared to conventional generalized spatial modulation system.Meanwhile

to reduce the complexity of signal detection in GPSM

this paper proposes a group detection algorithm base on GPSM.The simulation results show that the detection performance of the proposed algorithm is similar to that of the Maximum Likelihood（ML）method

while the complexity is reduced significantly.
