OFDM

直接序列扩频原理仿真.用ELAINX公司SYSTEMVIEW调试.(Direct Sequence Spread Spectrum simulation theory. SYSTEMVIEW ELAINX companies with debugging.)

说明：  polar码的SC译码，里面有详细的代码介功能绍pdf，非常细致(SC decoding of polar code, which has detailed code introduction function PDF)

说明：  OFDM的matlab注水算法编程算法。经典注水算法。用于频率资源分配。(OFDM's Matlab water injection algorithm programming algorithm. Classic water injection algorithm. It is used for the allocation of frequency resources.)

说明：  4. 试说明卷积编解码的工作原理： (1) 使用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编码、译码全部是自己编写代码(S-Function方式)，不是调用Simulink的已有编码、译码函数。 (2) 请在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。(4. Try to explain the working principle of convolutional codec: (1) Simulink was used to simulate convolutional coding, and Viterbi decoding method was used for decoding. The coding and decoding were all written by oneself (s-function method), rather than calling the existing coding and decoding functions of Simulink. (2) in the additive white gaussian noise channel, please draw the curve of the relationship between bit signal-to-noise ratio and bit error rate.)
