快速最小差错概率盲均衡算法

本文将Ｄａｏｂｅｎ Ｌｉ与Ｊ．Ｇ．Ｐｒｏａｋｉｓ提出的判决导引盲均衡代价函数应用于一种新的快速算法中。该代价函数可以保证在差错概率最小的同时，使总的信道响应最大限度地逼近所期望的（全响应或部分响应）信道特性。这种快速算法类似于最小二乘方算法，可以快速收敛。计算机模拟结果证实了该算法的有效性。

A Fast Minimum Error Probability Blind Equalization Algorithm

A new decision-directed cost function (criterion) for blind equalization proposed by Daoben Li and Proakis is firstly introduced in this paper. The cost function can simultaneously force the error probability as small as possible and the overall channel's impluse response function as close as possible to a desired one(full or partial response).The least-square algorithm which adopts the above cost function is also intreduced. Simulation results demonstrate the effectiveness of the algorithm.
