Distance Properties of Turbo-Codes and Viterbi Decoding Method

Publish Date: 25 Apr 2000

Abstract

Abstract

Turbo-codes are produced by parallel concatenation of recursive systemic codes (RSC), and its excellent performances are analyzed based on the free distance and bit error rate of the RSC codes. Adiago- nal interleave method is proposed based on the distance properties ofTurbo codes. With losing little gain, a viterbi decodingmethod to implementTurbo-codes decoding is putforward, withwhichthe correctness ofthe conclusions of this paper is proved by computer simulation.
