Abstract:
1. A decoding device, comprising: an input data storage memory storing a received data to be decoded; a viterbi decoder coupled to said input data storage memory to perform a viterbi decoding from a beginning time point of said received data until an end time point of said received data, and to output a first decoded data which is a result of said viterbi decoding of said received data from said beginning time point until said end time point, a likelihood information storage coupled to said viterbi decoder to store said path metric; a decoded data storage memory coupled to said viterbi decoder to store said first decoded data; a decoded data temporary storage coupled to said viterbi decoder to store said second decoded data; and a decoded data reconstruction circuit coupled to said decoded data storage memory and said decoded data temporary storage, to output a third decoded data based on said first decoded data and said second decoded data.
