Abstract:Low-Density Parity-Check (LDPC) decoders typically imple ment a single decoding algorithm or update rule, which nar rows down the design space of the decoder and maintains its overall simplicity. However, gear-shift techniques combine multiple decoding algorithms, update rules and quantization of the log-likelihood ratios (LLRs), allowing wider design space explorations as more parameters can be fine-tuned to a particular need. Gear-shift LDPC decoders have been shown to improve both the decoding throughput an… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
