Iterative receiver algorithms for multi-user detection and decoding are a solution for mitigating multiple-access interference (MAI) in multiple access communication systems. After several iterations they outperform noniterative schemes, while maintaining modest complexity. In this paper, we present an iterative receiver for multiple-antenna systems in frequency selective fading. Channel knowledge is not assumed to be available at the receiver. We propose a comprehensive algorithm that performs channel estimation, multi-user detection and decoding in an iterative manner. The multipath channel is estimated using several pilot symbols and soft estimates of data symbols. The performance of the receiver is evaluated by simulations.
