英文摘要：

The steepest descent and the two least-squares Constant Modulus Beam-forming Algorithm were introduced in this paper,then,the convergence of two algorithms on the performance and the steady-state performance in DS-CDMA system were analyzed by a MATLAB simulation , the results show that the performance of two algorithms in the Constant Modulus Beam-forming are obvious differences
