摘　　要：本文提出了一种适用于M-PAM和M-QAM的新的盲均衡算法:DDLMS-CMA算法。该算法克服了盲均 衡算法Sato、Godard残余误差大的缺点,又保持了快速收敛特性,并且收敛速率比BG算法快,是一种稳定的盲均 衡算法。In this paper, a new blind equalization algorithm, DDLMS-CMA algorithm, is proposed for M-PAM and M-QAM communication systems. This new algorithm overcomes the shortcoming of large residual error in Sato or Godard algorithm, and preserves the fast convergence performance. Its convergence speed is even faster than BG algorithm, As a stable blind equalization algorithm, it is useful in practice.
