摘要： Polar codes may be generated with a variable block length utilizing puncturing. Some puncturing algorithms consider punctured bits as unknown bits, and set the LLR for those bits to zero; while other puncturing algorithms consider punctured bits as known bits, and set the LLR for those bits to infinity. Each of these algorithms has been observed to provide benefits over the other under different circumstances, especially corresponding to different coding rates or different SNR. According to aspects of the present disclosure, both puncturing algorithms are performed and compared, and the algorithm resulting in the better performance is utilized for transmission.

摘要： The disclosure relates in some aspects to HARQ for communication of information (e.g., for wireless communication). In some aspects, if a device's first transmission including punctured encoded data fails, the device's second transmission (e.g., in response to a NACK) involves transmitting the punctured bits. In some aspects, the coding rate used for encoding the data for the first transmission is selected to meet an error rate (e.g., a block error rate) for the second transmission. The second transmission may also include repetition information that includes at least some of the encoded data. In some aspects, the puncturing may be performed according to a puncture pattern that is generated based on bit error probabilities of bit positions for encoded data.

摘要： A method of error correction using low density parity check (LDPC) codes is disclosed. A communications device receives a codeword and detects one or more bit errors in the received codeword using an LDPC code. The device then generates a corrected codeword based, at least in part, on a set of unsatisfied check nodes of the LDPC code. The device may determine that the one or more bit errors are associated with an absorption set of the LDPC code. The device may also determine a plurality of candidate codewords based on the set of unsatisfied check node and select the corrected codeword from the plurality of candidate codewords. Each of the plurality of candidate codewords may represent a valid codeword associated with the LDPC code.

摘要： Aspects of the disclosure relate to wireless communication devices configured to generate polar codewords utilizing a single master sequence constructed using density evolution with a nested structure for identifying the frozen bit locations and information bit locations. This single master sequence may be used for any codeword length N up to a maximum codeword length Nmax , and may further be utilized for any code rate R . For example, from the master sequence of length Nmax , a bit location sequence S with codeword length N (where N Nmax ) may be obtained by selecting the bit locations (indexes) in the master sequence corresponding to each bit location in S in the order provided in the master sequence.

摘要： Techniques are described herein to encode/decode information using a non-systematic Golay-based block code based on a systematic Golay-based block code. The non-systematic Golay-based block code may be generated based on information of the systematic Golay-based block code. In some examples, a subset of information of the non-systematic Golay-based block code may be based on a subset of information from the systematic Golay-based block code and a subset of information form the non-systematic Golay-based block code. The non-systematic Golay-based block code may be configured to support a plurality of lengths of output vectors or input vectors.
