摘要
Adaptive multi-user detection technology only needs the spreading sequence and the delay of the desired user. Its structure is simple, complexity is low. Therefore, it is suitable not only for mobile station but also for base station. The principle of adaptive minimum mean square error (MMSE) multi-user detection algorithm was expatiated. An adaptive MMSE multi-user detection algorithm based on recursive least squares (RLS) was proposed. Its iteration formula was deduced and the algorithm was simulated by MATLAB. The simulation shows that the BER performance of the algorithm is reduced with SNR increasing.
