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： 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.

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： 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： Methods, apparatuses, and systems for implementing error-correction in communication systems, particularly wireless communication systems, are provided. A Polar code-based encoding method combines first and second pluralities of information bits and error-correcting code bits, and a plurality of frozen bits, into an input vector. The input vector is encoded according to a Polar code to produce a first codeword, which improves the probability of successfully transmitting and receiving the codeword over a physical channel in the communication system.

摘要： General polar codes are disclosed that encode symbols of a q-ary alphabet, where q≧2. Systems and methods are also disclosed for performing code rate matching when using general polar codes. In one embodiment, a method performed at a transmitter includes receiving a plurality of bits at a polar encoder. The plurality of bits represent a plurality of q-ary symbols, where q>2. The method further includes encoding the plurality of bits using the polar encoder to generate a codeword of q-ary symbols represented by bits. The method further includes puncturing the codeword according to a puncturing pattern to obtain a punctured codeword having a reduced bit length.

摘要： A codeword is generated based on a segmentation transform and a Polarization-Assisted Convolutional (PAC) code that includes an outer convolutional code and a polar code, and based on separate encoding of respective different segments of convolutionally encoded input bits according to the polar code. Each segment of the respective segments includes multiple bits of the convolutionally encoded input bits for which the separate encoding of the segment is independent of the separate encoding of other segments. Separate decoding may be applied to segments of such a codeword to decode convolutionally encoded input bits corresponding to the separately encoded segments of the convolutionally encoded input bits.

摘要： Coding sub-channel selection involves, in an embodiment, determining, from sub-channels that are defined by a code and that have associated reliabilities for input bits at input bit positions, a first number of the sub-channels to carry bits that are to be encoded. A second number of the sub-channels, greater than the first number, are selected. The second number of sub-channels are selected to provide exactly the first number sub-channels to be available to carry the bits that are to be encoded.

摘要： A signature-enabled Polar code encoder and decoder are provided. Signature bits are inserted in some unreliable bit positions. Different signature bits are inserted for different receivers. For a given codeword, only the receiver with knowledge of the signature can decode the codeword. Cyclic redundancy check (CRC) bits may be included in the input vector to assist in decoding.
