周期高斯一介导、高斯二介导即高斯脉冲（即UWB信号）的功率谱图像，对应不同的占空比和不同的脉冲形式，随着阶数的增加中心频率右移，频谱也为高斯形式，且随着周期数增多，呈现线谱形式(Cycle Gaussian ordinary derivative, ie the Gaussian two-mediated Gaussian pulse (the UWB signal) of the power spectrum image, corresponding to different pulse duty cycle and a different form, with the increase of the order of the center frequency shifted to the right, the spectrum also Gaussian form, and with the number of cycles increased, showing the form of line spectrum)

说明：  This is very simple matlab code for laplacian pyramid used in contourlet transform.

单载波频域均衡，迫零算法以及MMSE算法的比较(Single-carrier frequency domain equalizatio，compare zeros and MMSE )

此函数为多径信道的仿真函数，非常不错的函数，有需要的请下载。(This function is multi-path channel matlab function, a very good program, there is a need for download.)

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.)

[LabVIEW]实现CRC校验，有些通讯协议需要用到CRC校验，所以很方便。([LabVIEW] implement the CRC, some protocols need to use the CRC, so it is convenient.)
