surface acoustic wave (correlator no temp diff)

利用FFT变换，对sine2进行频谱分析，画出频谱图 利用iir源程序对输入波形sine2进行低通滤波，并将结果输出至result.dat。 (Using FFT transform, spectral analysis of sine2, draw the spectrum graph use the input waveform iir source sine2 to low-pass filtering, and the results output to result.dat.)

This program is available to apply antenna theory and important to military. This uncludes Music algorithm, ESPRIT algorithm and conventional algorithm.

说明：  利用matlab仿真软件，实现8QAM调制。在实现时采用正交调幅的方式,某星座点在I坐标上的投影去调制同相载波的幅度,在Q坐标上的投影去调制正交载波的幅度,然后将2个调幅信号相加就是所需的调相信号。(Use of matlab simulation software to achieve 8QAM modulation. In achieving the adoption of quadrature amplitude modulation means of a constellation in the I coordinates of the projection to the modulation of the amplitude-phase carrier, in the Q coordinates of the projection to the range of carrier orthogonal modulation, and then the sum of two AM signals is the required phase modulation signal.)

最小费用流问题用于求解，图论中两地区运输费用最少的问题，本程序通过MATLAB解决这一问题(For solving the minimum cost flow problem in graph theory two least-cost regional transportation issues, the procedure to solve this problem through MATLAB)

通过一点来选取图像区域，手动选取图像中的一点，可以讲这个点周围的一定区域提取出来(Through a point to the image area，manual one point in a image，then we can get an area around this point)

Matlab, Laser, Hermite polynomals, m-file

说明：  the code is dealing with the detection of faces in an image. it is basically a face detection code
