Frequency domain time domain hybrid type equalizer

摘要

The channel decoder in order to achieve static and the dynamic multiple pass efficiency which are superior than the former decision return type equalizer, the frequency domain equalizer utilizes the frequency domain time domain hybrid type equalizer which is combined with the time domain equalizer efficiently. Frequency domain equalizer structure is included in the forward pass of the time domain of the decision return type equalizer which has the both of the frequency domain part and the time domain part which utilize common error vector. Individually, or, it can be adapted renewal to the tap (frequency bottle), completely inside the frequency domain without modifying the return filter. The efficiency which includes the efficiency of the channel which includes the noise which accompanies the deep notch mainly is improved, the frequency domain equalizer part is released from equalization of minimum phase zero of the channel.
