we propose an improved algorithm to solve the phase distortion and high bit error ratio problems during the signal transmission.Through setting the error threshold value
the algorithm can work between the CMA and LMS modes.The improved algorithm fully utilizes the faster convergence speed in CMA algorithm and LMS algorithm with good stability.The simulation results show that the proposed algorithm can increase the convergence speed of constellation points
concentrate the phase point
realize high and stable signal noise ratio high
and reduce the signal error rate to be 1/5of the previous result.
