Abstract

Space-time block coding (STBC) achieves the maximum diversity gain of a flat fading multiple input multiple output (MIMO) transmission link. For frequency selective fading, only a few receivers can be found in the literature. These are mainly trained and block based, such as time reversal STBC (TRSTBC). A non-block based blind receiver for STBC over dispersive channels has been derived previously, adding a new term to the cost function of the constant modulus algorithm to orthogonalise the outputs. In this paper a decision directed (DD) equalizer is used concurrently with the CMA receiver to achieve faster convergence. Simulation results demonstrate the benefit of the proposed approach in terms of convergence speed and bit error ratio in a doubly-dispersive scenario.
