摘要
提出了对信道可进行稳健均衡的相关均衡器，解决了由于信道传递函数的零点在单位圆外的分布引起的均衡结果发散问题。理论上相关均衡器对任意单位圆上无零点的信道都可进行稳健均衡；提出了非因果序列的双边展开理论，基于该理论和ＦＦＴ，导出了相关均衡器的横向滤波器结构和快速求解滤波器系数的算法；进行了仿真，结果令人满意．
Correlation equalizer, a recursive-formed equalizer, is proposed in this paper which caneliminate the divergence caused by zero points of channel response function outside unit circle, and cansuppress symbol interference theoretically in cases of most multiple path background. Its FIR form isalso developed based on FFT and noncausal two-side prediction. Simulations show that the FIRcorrelation equalizer has good performances even on negative coherent multiple path conditions.
