摘要

The multiuser detection is extensively concerned in CDMA. A novel multiuser algorithm is proposed on CMA. It has the characteristic of SIR highly and BER lowly. The essence of algorithm is that the coefficients of filter estimated are not directly. But first we estimate the coefficients of noise subspace,then synthesize the the coefficients of noise subspace and the coefficients of signal subspace and compare the CMA algorithm simulation resultion that show the efficiency of proposed algorithm.
