OFDM系统，子载波数目1024，前缀数目256，循环数目256，加入了高斯白噪声(OFDM system, the number of subcarriers 1024, the number prefix 256, the cycle number of 256, by adding a Gaussian white noise)

this file contains a good program in matlab for HAR wavelet

说明：  实现信号的频谱分析，性能分析，产生几个波形(For signal spectrum analysis, performance analysis, resulting in several waveform)

一个对数据进行频域分析的MATLAB程序，可以输出谐波幅值和相角(One pair of data in the frequency domain analysis of MATLAB program that can output harmonic amplitude and phase angle)

去斜率（strech）参考信号与回波信号混频后得到中频输出信号S(t)=Aexp(j*2*pi*f0*t+phase) 其中f0与回波延时的关系为： f0=k*delay_t K为线性调频斜率，delay_t为回波延时 将s(t)采样，FFT变换即可得到目标距离与频谱的关系。 Strech 信号测距 输入混频后的中频信号（图一），经采样及FFT变换得到频谱（图二） 再根据频谱与距离的关系式R=Tcf/2B显示出距离(图三) (Go slope (strech) obtained after the reference signal and the echo signal mixer IF output signal S (t) = Aexp (j* 2* pi* f0* t+phase) f0 and echo delay relationship: f0 = k* delay_t K chirp slope, delay_t the echo delay sampling s (t), the FFT transform to the target distance spectrum of relations. Strech signal ranging input mixer IF signal (Figure 1), sampling and FFT transform spectrum (Figure 2) according the the spectrum distance relationship R = Tcf/2B shows the distance (Figure 3))
