CrcStream stream checksum calculator

基于smi的自适应波束成形,本程序给出了基于smi算法的自适应波束成形(Based the smi adaptive beamforming, the program gives the the SMI algorithm-based adaptive beamforming)

计算语音信号的短时能量和过零率，显示它的时域波形(Calculated short-time speech signal energy and zero crossing rate, showing its time-domain waveform)

该部分代码可以实现图像的配准处理和图像对照。(image)

采用身高和体重数据作为特征，在正态分布假设下估计概率密度，建立最小错误率Bayes分类器，写出得到的决策规则.(Height and weight data used as the feature, under the assumption of normal distribution probability density estimation, establish Bayes minimum error rate classifier, written by the decision-making rules.)

说明：  上采样和下采样的matlab程序，以函数形式给出，有三种模式。(upsampling,downsampling,matlab,three mode)

维纳滤波器，用于在PSF已知情况下的反卷积(wiener filtering)

这是关于philips932源码GUI，我平时用的．(This is the source of philips932 GUI, I usually use.)

matlab 的基带仿真程序，使用二进制信源。加高斯白噪声(the matlab baseband emulator)

第一：边界加强，通过估计噪声和实际信号的比值，来确定各个尺度的细节系数，以达到噪声抑制和边界加强。第二，通过对小波分解的近似部分进行直方图均衡，达到加大整幅图片的对比度，而不太影响细节的目的。(First: to strengthen the border, through the estimates and the actual signal noise ratio, to determine the details of each scale factor, so as to achieve noise suppression and boundary strengthening. Secondly, the wavelet decomposition of the approximate portion of histogram equalization to increase the contrast of the whole images, and do not affect the details of the purpose.)
