OFDM时域定时测试，分别在高斯白噪声信道和瑞利信道中-OFDM time-domain time test, respectively white Gaussian noise channel and Rayleigh channel

产生高斯白噪声的C语言程序，经过测试，可以~~~好程序-Gaussian white noise generated C-language program, tested, can be a good program ~ ~ ~

高斯白噪声的生成程序，本科毕设要求参见标准测试模型，这是第二能量熵的matlab代码。- Gaussian white noise generator, Undergraduate complete set requirements refer to the standard test models, This is the second energy entropy matlab code.
