说明：  极化码编译码，采用SCL译码算法，同时参考协议3GPP TS 38.212，加了相应的速率匹配和交织。不过中间信道加噪仿真可能有些问题，希望参考者注意，如果可以指正的话就更好了。
(Polar code encoding and decoding utilize the Successive Cancellation List (SCL) decoding algorithm, with reference to the 3GPP TS 38.212 protocol. Rate matching and interleaving are applied accordingly. However, there may be some issues with noise simulation in the intermediate channel. Feedback on this matter would be greatly appreciated for improvement.)
