Computationally efficient turbo decoding with the bi-directional Viterbi algorithm (BIVA)

Abstract

An algorithm for decoding parallel concatenated codes (turbo codes) that replaces the BCJR algorithm with a new Viterbi type algorithm is presented. Replacement of the BCJR algorithm with the new algorithm results in a gain in computational efficiency with only a slight loss in BER performance.

Keywords:
BCJR algorithm Iterative Viterbi decoding Soft output Viterbi algorithm Turbo code Computer science Algorithm Viterbi algorithm Serial concatenated convolutional codes Sequential decoding Convolutional code Decoding methods Viterbi decoder Concatenated error correction code Berlekamp–Welch algorithm Block code
