Patent ID: 11139839

Abstract:
The disclosed structures and methods are directed to polar code decoders and methods for polar code decoding. A polar code decoder comprises an input logarithmic likelihood ratio (LLR) distributor, a master polar decoder module (PDM), at least one slave PDM, an intermediate LLR result combiner, and a decoded bit aggregator configured to generate a decoded codeword bit sequence. For each codeword node, each PDM partially decodes one or more sets of LLR subsets, which are sent to the intermediate LLR result combiner to generate an intermediate LLR result sequence. A first node decoding pipeline of the master PDM is configured to decode an intermediate LLR result sequence to generate at least one decoded node bit sequence. A polar code decoder with slave PDMs each having a second node decoding pipeline is also disclosed. A method for polar code decoding is also disclosed.
