Abstract

A differential detection scheme for a 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 natural 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
