OFDM系统中PAPR抑制（使用SLM方法）(PAPR reduction in OFDM systems)

说明：  自己编的关于改进的HHT的算法的部分程序，可以运行！效果还可以(Oneself make up about the improvement of the algorithm of HHT part of program, can run! Effect can also )

说明：  《MATLAB时频分析技术》例题matlab编程实现第十四章14.6-14.7(err)

time series In this example we will use a synthetic data set. To create our synthetic data we will make our unit of time 1000 years = 1 ky and sample a 500,000 year record in 2 ky increments. We first create a vector containing the times:

this is a matlab code for cdma it is a calculation of ber,snr etc.
