Beschreibung
Zusammenfassung:Previously, a TCM decoder has been using the Viterbi algorithm whose decoding process was complex. In order to reduce the complexity, the authors propose the 'modified decoding algorithm using the path back method', and the modified decoding algorithm extends the previous decoding algorithm to be able to be applied to the TCM decoder. Monte-Carlo simulation is used for analyzing the TCM performance and proving the efficiency of the proposed decoding algorithm.
