摘要 介绍了应用于DVB-C标准的QAM接收机中均衡器的盲均衡算法Stop-Go,RCA和Godard算法,分析了各种算法的收敛性,提出了避免系数收敛到局部收敛点的方法。 This paper introduces the blind algorithmsStop-Go,RCA and Godard,which are applied in QAM receiver of DVB-C standard.The covergence performance of the various algorithms is analysed,and the method of avoiding the coeffi-cients converging to the partial minimum points is put forward.[
