| 摘 要： | 在CMA算法基础上,利用多电平正交幅度调制(MQAM)信号的分布特点,提出了一种适合于MQAM数字通信系统的误差切换的盲均衡算法(ESA).理论分析和计算机模拟表明,该算法具有较快的收敛速度和较小的剩余误差,是一种很实用的盲均衡算法.

| Abstract: | In this paper, a new blind equalization algorithm based on the error switching is proposed for MQAM communication system, taking advantage of the distribution property of the constellation of MQAM. Theoretical analysis and computer simulations show that the new blind equalization algorithm with fast convergence and less remaining error is very useful in practical application. |
