摘要: 该文提出了一种适用于QAM通信系统的盲均衡算法。该算法克服了传统GSA,CMA等算法收敛后剩余 误差大的缺点,保持了较高的收敛速度,在均衡的同时能够自动补偿信道引起的相位误差。从计算机仿真结果可以 看出,该算法具有较好的均衡特性。Abstract: In this paper, a new blind equalization algorithm adapt to the QAM communication system is proposed, which overcomes conventional General Sato Algorithm (GSA), Gonstant Modulus Algorithm. (CMA), etc. algorithms larger residual error after convergence and still keeps a higher convergence rate, and it can recover the channel phase error automatically at the same time. The algorithms better equalization property is proved by the computer simulation results.
