Abstract :
A variable step size blind multi-user detection algorithm based on fuzzy control was proposed. It overcame the shortcoming of slow convergence rate in the fixed step algorithm. Step size of new algorithm could dynamically be adjusted by error and erroneous change, and it improves algorithm performance. The validity of new algorithm has been verified by computer simulation.
