This application provides a communication method and apparatus that can reduce the computational complexity of detecting information carrying a first bit, improve detection efficiency, and enhance communication performance. The method includes: determining a first signal based on a first sequence corresponding to the first bit information, wherein the first sequence is constructed based on the Kronecker product of a second sequence and a third sequence, the second sequence carrying the first bit of the first bit information and the third sequence carrying the second bit of the first bit information; and transmitting the first signal.

This disclosure presents embodiments of an error correction decoding method, an error correction coding method, an apparatus, an electronic device, and a medium. One specific implementation of the method includes: demodulating a symbol information sequence to obtain a demodulated information group sequence, wherein the demodulated information group sequence includes a demodulated bit information sequence and a confidence information sequence, and the demodulated bit information sequence is a bit information sequence with even parity characteristics; determining a codeword starting point code length information group sequence based on a preset code length information sequence; generating target codeword starting point information and target code length information based on the codeword starting point code length information group sequence and the demodulated bit information sequence; deblurring the demodulated bit information sequence based on the target codeword starting point information and target code length information to obtain a deblurred information sequence; and decoding the deblurred information sequence based on the confidence information sequence to obtain a decoded codeword sequence. This implementation reduces the waste of bandwidth and spectrum resources.
