In this paper we present a detailed analysis into the benefits and costs of merging decoders for different channel code types such as convolutional, turbo and LDPC codes. An ASIP (application-specific instruction set processor)-based framework for multi-code forward error correction (FEC) architectures is applied to implement three dedicated decoders for convolutional, turbo and LDPC codes respectively...
The use of rate-compatible error correcting codes offers several advantages as compared to the use of fixed-rate codes: a smooth adaptation to the channel conditions, the possibility of incremental Hybrid ARQ schemes, as well as simplified code representations in the encoder and decoder. In this paper, the implementation of a decoder for rate-compatible quasi-cyclic LDPC codes is considered. The decoder...
The use of rate-compatible error correcting codes offers several advantages as compared to the use of fixed-rate codes: a smooth adaptation to the channel conditions, the possibility of incremental Hybrid ARQ schemes, as well as sharing of the encoder and decoder implementations between the codes of different rates. In this paper, the implementation of a decoder for rate-compatible quasi-cyclic LDPC...
