| Abstract: | Two interesting space-time coding schemes for communication systems are the recently proposed differential space-time modulation (DSTM) scheme and the differential space-code modulation (DSCM) scheme. DSCM gives better performance than DSTM by exploiting the spatial degree-of-freedom to suppress interference. We show that, for DSCM, a maximum-likelihood (ML) demodulation approach, based on a deterministic channel model, improves the performance significantly compared to a previously proposed stochastic channel model based method |
