CAM algorithm has the characteristic of simple architecture,less computing complexity and no occupation of extra channel bandwidth.More and more attention has been paid to the CMA algorithm in the application of wireless communication.Proceeding from the CMA algorithm,a M22 CMA architecture which can be applied to complex signal is derived in this paper.Matlab emulation and VHDL verification for the algorithm were performed with QPSK signal.The simulation and experimental results show that the performance of the algorithm is reliable,and it can be used to equalize QPSK signal in the wireless channel.
