Near-optimum decoding of product codes: block turbo codes

IEEE Transactions on Communications, 1998
Summary: This paper describes an iterative decoding algorithm for any product code built using linear block codes. It is based on soft-input/soft-output decoders for decoding the component codes so that near-optimum performance is obtained at each iteration.

A Hybrid Decoder for Block Turbo Codes

IEEE Transactions on Communications, 2009
We propose a novel iterative decoder for block turbo codes (BTCs). The proposed decoder combines soft-input/softoutput (SISO) and hard-input/hard-output (HIHO) constituent decoders in order to obtain better error performance and reduce the computational complexity compared to classical BTC decoders. We show that the new decoder, called 'hybrid decoder',

Reduced-search SOVA for block turbo codes

IEEE International Conference on Communications, 2003. ICC '03., 2004
In this paper, we propose an efficient reduced-search SOVA (soft output Viterbi algorithm) for block turbo codes. To reduce complexity, the decoder selects a part of the existing paths using the statistics of the path metrics. In addition, we compensate for the performance degradation incurred from soft output values at the parity part of the trellis ...

How we implemented block turbo codes?

Annales Des Télécommunications, 2001
This paper presents a block turbo decoding algorithm, from its theory to its implementation in a programmable circuit. In this study, we discuss the two prototypes realized. It will be possible to compare the complexity of the core of the process, which is the elementary decoder, thanks to the choice of essential parameters.
