Embodiment 1
[0066] This embodiment includes 4 transmission blocks at the sending end, and each transmission block contains an information sequence u with a length of 32 bits, wherein 29 bits are the same information bits, and 3 bits are different information bits, and each transmission block has an information sequence u Add a 24-bit CRC check code, perform polar coding and BPSK modulation, and transmit in the AWGN channel, where the code length is 128 bits. At the receiving end, the polar code-based 5G broadcast channel combination receiving method proposed by the present invention is used for decoding. The relationship curve of SNR and BLER is obtained by simulating the communication link. At the same time, the effect of the present invention is verified by comparing with the BLER obtained by receiving and simulating each transmission block separately under the same conditions. figure 1 It is the scrambling and encoding process in the encoding process of "a method for combining and rec...
