matlab没有提供画椭圆的函数，该函数在获得椭圆中心 长轴轴 短轴后进行画椭圆，其中使用复变函数(did not draw an ellipse matlab function, the function in the long axis of the axis minor axis of the ellipse center painted oval, which use the complex function)

该文件含有高斯信号产生的完整代码，用matlab编写的，并含有详细的注释,另外还有两个小波基的使用的详细注解(This file contains the complete code for the Gaussian signal is generated, using matlab, and contains detailed notes, in addition to the use of two small Porgy detailed comments)

BER verses SNR in ofdm with amplifier: The BER performances of OFDM systems over the AWGN channel are given by the BER where N=512. We see that SNR required for BER=10-3 No channel coding scheme is adopted. Therefore, BER is a bit higher. The results with 16 QAM show that the required Signal to Noise Ratio (SNR) for BER=10-2 is almost the same. This is because the noise is the dominant.

使用matlab实现背景和前景分离，运动目标跟踪识别，一个很不错的程序(Using matlab to achieve separation of background and foreground, moving target tracking and recognition)
