In this paper, the authors prove that the differential space-time modulation techniques proposed in literature provide a full spatial diversity. Based on that, the authors propose an antenna selection scheme called general N-out-of-M antenna selection technique for wireless communications channels utilizing differential space-time modulation. The simulation shows that differential detection associated with our proposed technique provides much better bit error performance over that without antenna selection, and even over coherent detection without antenna selection at certain signal-to-noise ratios.
