Abstract

In this paper, multiple-symbol differential detection (MSDD) is applied for differential unitary space-time- frequency coding (DUSTFC) scheme over frequency selective fading multiple-input multiple-output (MIMO) channels to compensate for the performance loss of conventional differential detection comparing with coherent detection. The decision metrics of time and frequency domain MSDD for DUSTFC are derived by considering the time and frequency domain fading autocorrelation respectively. Simulation results demonstrate that extending the observation interval of MSDD can effectively lower the error floors for DUSTFC schemes coded on both time and frequency domain.
