摘要 为降低基于Parzen窗随机盲均衡(SQD)算法在传输信号采用高频带利用率QAM信号时的计算复杂度,提出一种低复杂度SQD算法(LCSQD).将判决区域从整个星座修改为一个以均衡器输出为圆心,半径为可调的圆,计算量较少,并且不会随QAM阶数的增加而增加.采用16QAM和64QAM调制信号测试了不同判决半径时LCSQD算法的性能.结果表明,两种算法的稳态剩余ISI相接近时,LCSQD算法的收敛速度快于SQD算法. The blind equalization algorithm based on Parzen window method （SQD algorithm） has high computational complexity when systems use high bandwidth-efficiency quardrature amplitude modulation （QAM）. A low complexity SQD algorithm （LCSQD） was developed. The judged region of the proposed algorithm was changed from the whole constellation to a circular region of the constellation, whose center was the equalization output and radius could be adjusted experimentally, and which leaded to a low computational requirement. Simulations for 16QAM and 64QAM show that the proposed algorithm has a faster convergence speed than that of SQD algorithm when the residual ISI is the same.
