An Adaptive Multi-user Detection Algorithm Based on RLS

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 onlv 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 reeursive least squares (RLS) was proposed.Its iteration formula was deduced and the algorithm was simulated bv MATLAB.The simuiation shows that the BER perfornlauce of the algorithm is reduced with SNR increasing.
