A simple scheme is proposed in order to reduce the computational complexity. The performance of MAP Turbo JD algorithms are simulated for a TD-SCDMA uplink transmission. The result shows that the simple MAP Turbo JD scheme yields much better performance than the linear joint detection, and its computational complexity is much lower than the optimum algorithm.
