| Abstract(in English) | In our PRML systems, we employ a noise whitening matched filter having minimum-phase to avoid emphasizing high frequency noise and coloring noise and combine it with Viterbi detector with path feedback. First, the minimum-phase, noise-whitening matched filter which consists made of a transversal filter and a low-pass filter is described. Then, the error rate performance is obtained by computer simulation, and the performance is compared with that of the combination of a minimum-phase, noise whitening matched filter and fixed delay tree search with decision feedback (FDTS/DF). The results show that Viterbi detector with path feedback can improve the signal-to-noise ratio over that of FDTS/DF. |
