几点说明： 1、source_main.m为主函数，qpsk.m和spread.m为子函数； 2、在matlab工程目录下运行source_main.m即可； 3、为方便大家理解，特以P-CCPCH信道的处理进行了举例，若大家认为资料有用的话请回帖， 我会将整个WCDMA下行信号源的matlab代码提供给需要的人； 4、为方便初学者学习，特提供了我自己开发时参考的3GPP资料，并在关键位置做了记号。 -Some explanations: 1, source_main.

This code is intended to provide a reference model for the standard and has been written with a focus on correctness, rather than on simulation speed. This code is also intended to provide a platform for research on enhancements to the New Radio pola

Matlab simulations of the encoder and decoder for the New Radio LDPC code from 3GPP Release 15. The corresponding standards document (TS38.212)
