Viterbi decoding system including variable-order equalizer.

摘要

A Viterbi decoding system includes a characteristic estimator (150) for estimating a characteristic of a system, and an equalizer (120) for receiving an input signal from the system and for equalizing a waveform of the input signal so that an equalized waveform of the input signal is varied based on the characteristic of the system estimated by the characteristic estimator. A Viterbi decoder (130) generates an output signal showing a maximum-likelihood path by using the equalized waveform of the input signal from the equalizer.
