| 摘 要： | 在对常模算法 (CMA) 和改进常模算法(MCMA)的研究基础上,提出了一种改进的变步长双模算法(Variable Step-size MCMA-DD).改进算法通过误差信号自动地调节步长,从而调节算法的收敛速度.通过仿真表明,改进算法具有与MCMA-DD算法相近的误码性能,但是很大程度地加快了算法的收敛速度.

| Abstract: | In this paper,an improved variable step-size MCMA-DD algorithm is introduced based on the study of CMA and MCMA. By changing step-size factor in terms of error signal automatically,the improved algorithm can adjust the convergence speed. The computer simulation shows that the improved algorithm has similar error performance with MCMA-DD algorithm,while it accelerates the convergence speed tremendously. |
