Abstract: 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<N. An ordered sequence of length Nref, instead of a longer ordered sequence of length N, may be used in selecting the sub-channels. The input bits are encoded to generate a codeword, and the codeword is transmitted.

Abstract: Method and apparatus for generating a codeword by interleaving information and assistant bits. An interleaved sequence of information bits and assistant bits is generated according to an interleaving order. The interleaving order is selected to reduce a number of information bits occurring before a first assistant bit and further reduce each subsequent number of additional information bits occurring between assistant bits. The interleaved sequence is encoded using a polar code to generate a codeword, and the codeword is transmitted.

Abstract: Disabled input bit positions of an input bit vector that is to be encoded are determined based on non-contiguous subsets of consecutive coded bit positions that are to be punctured from a codeword of a polar code. The input bit vector is encoded according to the polar code to generate a codeword, by applying information bits to input bit positions of the input bit vector other than the disabled input bit positions. The non-contiguous subsets of consecutive coded bit positions are punctured from the codeword to generate a punctured codeword, and the punctured codeword is transmitted. In some embodiments, the non-contiguous subsets include a first subset that includes a first coded bit position and a second subset that includes a last coded bit position. The polar code could be a chained polar code, for example.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Methods and apparatuses for implementing error-correction in communication systems, particularly wireless communication systems. Input bits are encoded according to a chained generator matrix to generate a codeword, and the codeword is transmitted. The chained generator matrix includes a first subset of entries corresponding to a first subset of entries in a base generator matrix for a chained polar code, and a second subset of entries that are different from a second subset of entries in the base generator matrix. A chained generator matrix could be constructed, for example, by applying a chaining matrix to the second subset of entries in the base generator matrix, to produce the second subset of entries in the chained generator matrix.
