static viterbi equalizer to mitigate the ISI in frequency selective channel.

均衡效果好，这是基于最大似然估计的均衡器-With the development of high-speed optical fiber communication systems, polarization mode dispersion (PMD) has become a vital limiting factor. However, the traditional compensation methods which in optical domain have the d

用Viterbi algorithm筛选经过含白噪声的信息。equalizer为采用Viterbi algorithm，有效减少ISI(码间串扰)，detector为简单的检验器。对比两者的误码率。信息数量为10001bit-using Viterbi algorithm method selecting the data. compared with simple detector. data length are 10001bits. Viterbi algorithm can reduce
