小波变换matlab程序,实现小波变换的程序(Wavelet transform matlab process procedures for the realization of wavelet transform)

信号经过两个独立的信道传输，两个信道的信道复增益分别为 和 。 是独立同分布的复高斯随机变量，实部虚部独立、均值为0，实部虚部的方差都是1。采用某分集技术后输出的信噪比为 ，其中 是常数， 是在 之间均匀分布的随机变量。请就不同的 、 ，用仿真的方法画出 的累积分布函数。(signal after two independent Channel Tunnel, Channel 2 Channel Minute respectively, and gain. Independence is the same complex Gaussian distribution of random variables, is the imaginary part of the Department of independence, mean 0 and the real part of the imaginary part is a variance. Using a diversity of the output signal-to-noise, which is constant, is the uniform distribution between random variables. Please different, and simulation methods paint the cumulative distribution function.)

matlab中模拟的两道地震信号反射同相轴，用riker子波模拟。(matlab to simulate the two-channel seismic reflection phase axis signal with riker sub-wave simulation.)

此程序实现压缩感知方法与最小二乘方法在超宽带信道估计中实现信道估计的MSE对比。(This program is compressed sensing method with the least squares method is implemented in ultra-wideband channel estimation channel estimation MSE contrast.)

DD算法实现语音增强，噪声谱估计，根据寂静帧和后面能量的对比来估计(DD algorithm speech enhancement, noise spectrum estimation, based on comparative silence frame and rear energy to estimate)

说明：  马氏距离的仿射不变性删除误匹配特征点 对，据此可求取2幅源图像间的仿射变换参数(Mahalanobis distance of the affine invariant features remove the false matching points Yes, according to the source to obtain two parameter affine transformation between images)

画出具有不同频率，相位的正弦信号及其DFT序列，并检验信号正交性(Draw different frequencies ,different phase of the sinusoidal signal ,and the DFT sequence, then check the signal orthogonality)
