差分调制与解调
此代码通过随机生成二进制码,对其进行二进制差分调制,以及加入高斯白噪声后对其解调计算误码率,绘制出其输入信噪比与输出信噪比的实验曲线及理论曲线的比较。(This code generates binary codes randomly, modulates them by binary differential modulation, demodulates them with Gauss white noise and calculates the bit error rate, draws the experimental curve and theoretical curve of their input signal-to-noise ratio and output signal-to-noise ratio.)

time_varying_multipath_channel
说明: 单频信号经过多径时变信道后,输出信号的包络随时间随机起伏,输出信号的频谱从冲激谱变成一个窄带频谱。径数位20,变化频率从0—2HZ随机均匀抽取。(Single-frequency signal through time-varying multipath channel, the output signal envelope random fluctuations over time, the output signal from the impulse of the spectrum into a narrow-band spectrum spectrum. Digital Drive 20, changes in frequency from 0-2HZ uniform random samples.)

Filter
这是一个去极值滑动窗口数字滤波器算法,在ADC采样的时候可以用这个算法去除脉冲干扰。(This is digital filter algorithm which removes extreme value,and it works just like a sliding window, we can use this algorithm to remove glitches in ADC sampling。)

ECA_RD_DRM
说明: 产生复高斯的白噪声,这和matlab 自带的不一样,容易理解,但是经对比还是和自带的有区别的(AWGN noice we are very nice. please try to run it snd you will find you are good too.)
