Abstract

Abstract: A variable step-size blind multi-user detection algorithm based on fuzzy control is proposed.It overcomes the shortcoming of convergence rate slow in the fixed step algorithm.Step of new algorithm can dynamically be changed by error and erroneous change.And it improves the performance of the algorithm.Through MATLAB simulation，the validity of new algorithm is verified.

Key words: blind multi-user detection, fuzzy control, variable step-size
