Abstract :
Widely linear leaky least mean square (WL LLMS) type algorithm and its modified edition with time varying step size and leakage parameter for multiple access interference (MAI) suppression in direct-sequence code-division multiple access (DS-CDMA) system is introduced and analyzed. The better performance of new algorithm is shown by simulation.
