[0021] In order to have a clearer understanding of the technical features, objects and effects of the present invention, the specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0022] like figure 1 Shown is a schematic diagram of a polar code construction method based on universal partial order UPO and genetic algorithm under a SCL decoder of the present invention. According to the improved UPO algorithm, the method selects reliable bit channels (information bits), which are not reliable. The bit channel (frozen bit) and the uncertain bit channel (may be information bit or frozen bit); the genetic algorithm is improved, and the convergence speed of traditional genetic algorithm is accelerated by introducing Hamming distance initialization and elite individual protection mechanism and precision; according to the improved genetic algorithm to find the optimal solution in the uncertain bit channel, that is, ...
