双音多频 DTMF（ Dual Tone Multi-Frequency ）信号，是用两个特定的单音频率信号的组合来代表数字或功能(DTMF DTMF (Dual Tone Multi-Frequency) signals, use of two specific combinations of tone frequency signals to represent the number or function)

Beamforming using Leas Mean Square

说明：  matlab 实现的全景图像拼接，希望对大家能有所帮助(matlab implementation of the panoramic image mosaic, we want to help)

求一维序列x(n)的离散Fourier谱分析，s(0:m)离散功率谱，c(0:m)振幅谱，cta(0:m)位相谱，其中m=[n/2.]。(Discrete Fourier spectrum of one-dimensional series)

均匀量化和非均匀量化在性能上存在着显著的差异，这种差异可以用信号通过量化器后的量躁比来反映出来。本程序用曲线表示了理论和实际两个方面下两种量化的量躁比。从而可观察他们的性能上的差别。(There are significant differences with the function between Uniform quantization and non-uniform quantization ,which can be quantified by SNR from the quantizer.This program use the curves to denote the SNR of theory and practical signal.Then we can observe the performance of the differences.)

函数的作用是执行1/4像素精度的运动估计 f1是参考帧,f2是匹配帧 函数首先对初始图像进行分辨率提高4倍的双三次插值 再进行基于块匹配的全搜索运动估计(Full search block matching based motion estimation)

CDMA detection including transmitter and receiver

一维FDTD仿真传输线理论，分别设定了不同的电源电阻和负载电阻，并且可以自动生成.avi文件播放。(One-dimensional FDTD simulation of the transmission line theory, were set up different power resistance and load resistance, and can automatically generate .avi file playback.)

分支定界 MATLAB编程 分支 定界 剪枝 取整数解(Branch and bound MATLAB programming branch and bound pruning rounded solution)

说明：  该程序主要用于将UFF格式的文件转换成matlab的mat格式文件。(it can change the uff file to the mat filte which is used to store the data in matlab.)
