摘要： In a layered coding approach, a code configuration parameter of a polar code is determined, and encoding graph parameters are determined based on the determined code configuration parameter. The encoding graph parameters identify inputs for one or more kernel operations in each of multiple encoding layers. Information symbols are encoded by applying the one or more kernel operations to the inputs identified in each encoding layer in accordance with the determined encoding graph parameters.

摘要： A sub-channel to carry an information bit, in input bits that are to be encoded, is selected from each of multiple subsets of sub-channels that are provided by a length N polar code. The subsets include sub-channels that are associated with respective overlapping constituent polar codes of the length N polar code. The constituent polar codes are of length Nref

摘要： An assistant sub-channel to carry a decoding assistant bit, in input bits that are to be encoded, is selected from each of a plurality of non-adjacent segments. Each segment includes a subset of sub-channels with associated reliabilities. Some embodiments also involve grouping the sub-channels into the segments. After a target number of assistant sub-channels have been selected, the input bits are encoded to generate a codeword, and the codeword is transmitted. Assistant sub-channel selection could involve iterations to select assistant sub-channels at each iteration, until at least the target number of assistant sub-channels have been selected.

摘要： An improved method of computer communication and networking with error-correction encoding and transmission using a punctured polar code construction that is based on polar code decomposition is provided. Advantageously, this allows sorting of a reliability sequence to be performed for a reduced-length vector to identify the information bit positions in the reduced-length polar code vector. Polar code decomposition is used to determine a number of information bits allocated to given reduced-length vector (e.g., K0 and K1). The polar code construction is a function of a puncturing pattern. In some embodiments, the puncturing pattern is a shortening pattern.

摘要： One or more codewords are generated by encoding input bits at input bit positions onto sub-channels that are provided by a code. Each of the sub-channels has an associated reliability of correct decoding of an input bit at an input bit position. Each codeword is transmitted to a decoder, and a word based on each transmitted codeword is received at the decoder. Each received word is decoded, and the reliabilities of the sub-channels are determined based on decoded bits and known input bits from which each codeword was generated. An indication that is based on the determined reliabilities of the sub-channels, such as an indication of the determined reliabilities, is transmitted to the encoder, and may be used by the encoder in selecting the sub-channels for encoding subsequent input bits, for example.
