Strategies for Reducing Decoding Cycles in Stochastic LDPC Decoders

This brief presents three strategies, including initialization based on Look Up Table (LUT), postprocessing based on bit flipping and hard decision based on the posterior information, to reduce the number of decoding cycles (DCs) for stochastic …

An Efficient Multirate LDPC-CC Decoder With a Layered Decoding Algorithm for the IEEE 1901 Standard

An area-efficient multirate low-density parity-check convolutional code (LDPC-CC) decoder is presented in this brief. Using the layered decoding algorithm, the decoder achieves a bet- ter performance than the message-passing algorithm; the extrinsic- …
