Abstract

An iterative receiver is proposed for a wireless communication system employing multiple transmit and receive antennas. The transmitted symbol sequences are space-time encoded. By exploiting the inherent structure in the space-time encoded data sequence, the receiver is able to significantly improve the initial estimate of the unknown channel leading to significant performance gains in terms of the bit-error-rate (BER) as a function of the signal-to-noise ratio (SNR). Computer simulations demonstrate the efficacy of the scheme in single-user and multi-user environments.
