    Abstract: The present disclosure relates to encoding method and devices. One example method includes determining N to-be-encoded bits, where the N to-be-encoded bits include information bits and frozen bits, obtaining a first polarization weight vector including polarization weights of N polarized channels, where the N to-be-encoded bits correspond to the N polarized channels, determining positions of the information bits based on the first polarization weight vector, and performing polar encoding on the N to-be-encoded bits to obtain polar-encoded bits.

    Abstract: A signal processing method and an apparatus thereof. A first signal is received, wherein the first signal includes x symbols. N types of quantization levels are determined based on a signal distribution parameter of the first signal. A second signal is determined based on the first signal. Quantization processing is performed on the second signal to obtain x groups of first quantization results, wherein the x symbols are in one-to-one correspondence with the x groups of first quantization results. The x groups of first quantization results are mapped to a quantized first signal, wherein the quantized first signal includes x quantization levels, and each group of first quantization results is mapped to one of the N types of quantization levels. Signal processing is performed on the quantized first signal.

    Abstract: A polar code coding/decoding method, a sending device, and a receiving device are disclosed. The method includes: selecting, by a sending device, K non-punctured-position sequence numbers as a reference sequence number set based on a quantity K of information bits and a reliability-based order of N polarized channels of a polar code whose code length is N, where a reliability of a polarized channel corresponding to any sequence number in the reference sequence number set is greater than or equal to reliabilities of polarized channels corresponding to remaining (N−K) sequence numbers; determining, by the sending device, an information-bit sequence number set based on a determining condition and the reference sequence number set; and performing, by the sending device, polar coding on to-be-coded bits based on the information-bit sequence number set.

    Abstract: Embodiments of this application disclose a polar coding method, apparatus, and device, so as to reduce storage overheads of a system. A sequence for polar coding is obtained based on a length M of a target polar code, wherein the sequence comprises L sequence numbers, ordering of the L sequence numbers in the sequence is the same as ordering of the L sequence numbers in a maximum mother code sequence, wherein the maximum mother code sequence is obtained by sorting N sequence numbers of N polarized channels in ascending order or descending order of reliability metrics, wherein L and N are integer power of 2, M is smaller than or equal to L, L is smaller than or equal to N.

    Abstract: A decoding method and apparatus are provided, to improve a degree of parallelism in decoded bit decisions and reduce a decoding delay. The method includes: performing a hard decision on each LLR in an inputted LLR vector having a length of M to obtain a first vector, where M≤N and N is a length of to-be-decoded information; sequentially performing negation of some elements of the first vector to obtain L vectors; and then determining decoding results of the LLR vector based on the L vectors.
