[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer, the implementation process and performance analysis of the present invention will be further described in detail below in conjunction with the accompanying drawings and simulation examples.
[0030] See Figure 4 , Introduce the source coding method based on polarization code of the present invention:
[0031] First determine the symbol value set of the source recovery signal, and then use the best symbol-to-bit mapping rule to serially map the source symbol sequence into a bit soft information sequence, and perform polarization coding on the bit soft information sequence The serial offset coding is to find the coding path with the largest reliability value and the bit sequence corresponding to the coding path, and finally through the reliable bit set, select the most important part of the bits from the bit sequence as the coding result.
[0032] See Figure 5 , Specifically i...
