Abstract
According to at least one embodiment, a signal processor apparatus includes a Viterbi decoder, a processor, and an adjustment module. The Viterbi decoder calculates a branch metric based on an input signal. The processor outputs a processing result correlated with a processing result of the Viterbi decoder. A latency of the processor for the input signal is lower than a latency of the Viterbi decoder. The adjustment module adjusts a first parameter for calculating the branch metric based on the processing result of the processor.
