Performance of Differential Space-Frequency Modulation under Time-Varying Frequency-Selective Fading Channels

摘要：

In this paper two differential subcarrier grouping schemes named MSSG and SSSG are firstly analyzed under the same mathematic model. Then we describe two differential space-frequency modulation schemes combining differential space-time modulation and orthogonal frequency division multiplexing. They are F-DSFMInwhich differential encoding is carried out in frequency direction and T-DSFMInwhich differential encoding is carried outIntime direction. Analysis and simulation results show that F-DSFM is suit for strong time-selective fading channels and T-DSFM is suit for strong frequency-selective fading channels,under time-varying frequency-selective channels subcarrier grouping scheme SSSG is better than MSSG especially for low data rate transmission.
