Combining serial and parallel decoding for turbo codes

Turbo Decoding for PR4: Parallel Versus Serial Concatenation

Recent work on the application of turbo decoding techniques to partial response class 4 (PR4) channels has focused on parallel concatenation systems that require three APP detectors. A simplified serial concatenation system will be presented that uses as its outer code a single convolutional code and as its inner code the partial response channel. An extension of this serial concatenation syste...

Full-parallel architecture for turbo decoding of product codes

A full-parallel architecture for turbo decoding, which achieves ultrahigh data rates when using product codes as error correcting codes, is proposed. This architecture is able to decode product codes using binary BCH or m-ary Reed-Solomon component codes. The major advantage of our architecture is that it enables the memory blocks between all half-iterations to be removed. Moreover, the latency...

Towards an optimal parallel decoding of turbo codes

High throughput decoding of turbo-codes can be achieved thanks to parallel decoding. However, for finite block sizes, the initialisation duration of each half-iteration reduces the activity of the processing units, especially for higher degrees of parallelism. To solve this issue, a new decoding scheduling is proposed, with a partial processing overlapping of two successive half iterations. Pot...
