Abstract :
In this paper, a blind space-time decoding (BSTD) algorithm is proposed for the down-link of a space-time coded multicarrier CDMA system with multiple transmit and receive antennas used. The proposed BSTD algorithm is an iterative algorithm using Chi and Chen´s computationally efficient fast kurtosis maximization algorithm with super-exponential convergence rate. Some simulation results are presented to support the efficacy of the proposed BSTD algorithm
