In this paper, an adaptive space-time receiver for cooperative relay networks is proposed. Using cooperative amplify-and-forward relay nodes, it is possible to increasing the rank of the multiple-input multiple-output (MIMO) channel. The proposed receiver is based on a joint adaptive iterative detection and decoding algorithm, adaptively cancels co-channel interference and eliminates the multiple access interference. The least mean square (LMS) algorithm is used for the adaptive receiver. Simulation results show that the proposed scheme achieves better bit error rate (BER) performance compared with the traditional MIMO scheme. ©ICROS.
