Embodiment 1
[0082] figure 1 It is a schematic diagram of the structure and connection relationship of a transmission system based on prime-code interleaving and polar-code encoding in the present invention.
[0083] Depend on figure 1 It can be seen that the information bits to be transmitted enter the channel module through the sending signal processing module in the system, and then are received, demodulated and decoded and output by the receiving signal processing module.
[0084] The interleaving parameter control unit is respectively connected with the prime code interleaving unit and the prime code deinterleaving unit;
[0085] The system parameter initialization module is connected to the CRC check unit, Polar encoding unit and modulation unit in the sending signal processing module, and also connected to the demodulation unit, Polar decoding unit and CRC dechecking unit in the receiving signal processing module.

Embodiment 2
[0127] During specific implementation, the frame length of the Polar code that the system parameter initialization module initializes in step 1 is N=1024 bits, and the information bit length K is 488 bits, and the list length L=2, and the CRC length is 24 bits; The method is BPSK; the total number of frames is 2000; the maximum number of error frames is 100;
[0128] Skip step 4 and step 8; the other steps are advanced in sequence, and the channel in step 6 is additive noise. The specific simulation uses the randn function or awgn function in the matlab software to realize the Gaussian white noise channel;
[0129] Based on different signal-to-noise ratios, that is, EbN0, repeat step 1 to step 12, where the values of EbN0 are 1, 1.2, 1.4, 1.6, 1.8 and 2, and the frame error rate BLER under different signal-to-noise ratios is obtained And the bit error rate BER is shown in Table 1 below:
[0130] Table 1 does not adopt the frame error rate and bit error rate results (2000 fr...
Embodiment 3
[0133] Compared with Embodiment 2, the parameters and operation steps selected in this embodiment remain unchanged except that the frame length of Polar encoding is N=256 bits, the number of frames=1000 frames, and the information bit length K is 104 bits. After simulation, the frame error rate BLER and bit error rate BER obtained under different signal-to-noise ratios are shown in Table 2 below:
[0134] Table 2 does not adopt the frame error rate and bit error rate results (1000 frames, N=256) of prime code interleaving in step 4 and step 8
[0135] EbN0 1 1.2 1.4 1.6 1.8 2 BLER 0.4310 0.3300 0.2463 0.1616 0.1175 0.0860 BER 0.1310 0.0909 0.0708 0.0462 0.0280 0.0211
