In this paper, a differential detection scheme for Multiple-Input Multiple-Output (MIMO) DS/CDMA link is presented, where neither the transmitters nor the receivers know the Channel State information (CSI). The transmission provides for full spatial diversity gain by a simple detection scheme, which is the nature extension of differential detection combined with an Orthogonal Transmit Diversity (OTD) approach. Moreover, a capacity analysis for this scheme is illustrated. The capacity analysis and simulation results show that 3 dB loss is paid for differential detection compared to coherent detection.
