Abstract: Embodiments of the present application relate to a method for implementing Turbo equalization compensation. The equalizer divides a first data block into n data segments, where D bits in two adjacent data segments in the n data segments overlap, performs recursive processing on each data segment in the n data segments, before the recursive processing, merges the n data segments to obtain a second data block; and performs iterative decoding on the second data block, to output a third data block, where data lengths of the first data block, the second data block, and the third data block are all 1/T of a code length of a LDPC convolutional code.

Abstract: This application discloses a modulation/demodulation and encoding/decoding method and belongs to the field of communication technologies. The modulation and encoding method includes: grading to-be-transmitted bits into a plurality of levels; encoding a plurality of levels of bits obtained through grading to obtain a plurality of levels of codewords; and mapping the plurality of levels of codewords to a symbol in a staggered manner, where the plurality of levels of codewords include a first codeword, the first codeword is located at a Yth level of the plurality of levels of codewords, and the first codeword overlaps at least one codeword at any level other than the Yth level. In this way, codewords at different levels are associated by using a symbol to which the codewords are mapped, and an overlapping part between a plurality of codewords can assist in demodulating the codewords.

Abstract: The present disclosure relates to parameter updating methods. In one example method, a parameter in a neural network model is updated for a plurality of times through a plurality of iterations. The plurality of iterations include a first iteration period and a second iteration period. In the first iteration period, an inverse matrix of an additional matrix of the neural network model is updated once based on a quantity of iterations indicated by a first update stride. In the second iteration period, the inverse matrix of the additional matrix of the neural network model is updated once based on a quantity of iterations indicated by a second update stride, where the first iteration of the second iteration period is after the last iteration of the first iteration period in an iteration sequence, and the second update stride is greater than the first update stride.
