Abstract
This paper presents a study into the performance, reliability and costs of channel decoders for different channel codes such as Convolutional _turbo, Viterbi, Reed Solomon and LDPC codes. A framework for multi-code forward error correction (FEC) architectures is identified to implement four dedicated decoders for convolutional_turbo, Reed Solomon and LDPC codes as well as a single decoder capable of decoding all the four. Performance estimations for all the four architectures are presented to provide a clear and fair comparison between single-mode and multi-mode decoders.
