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)

通信系统，基于MATLAB对OFDM进行仿真，结果有调制解调图，信噪比，眼图等等。( Communications systems, based on OFDM MATLAB simulation results have modem map, SNR, eye and so on.)

说明：  这个Matlab程序实现了MAP算法-最大后验概率算法，同时包括对算法有：卷积编码、卷积解码，BPSK，AWGN。同时绘制它的误码率和SNR(信噪比)。(The Matlab program achieved a MAP algorithm- maximum a posteriori probability algorithm, at the same time including the algorithm are: convolutional coding, convolution decoding, BPSK, AWGN. At the same time rendering its error rate and SNR (signal to noise ratio).)

bp 网络逼近函数,作正弦函数逼近.对初学者来说是不错的例子.(bp network approximation functions for sine function approximation. For beginners is a good example.)

LMS自适应均衡仿真程序,多级抽头,有信噪比条件(LMS adaptive equalizer simulation program, multi-level tap, has SNR)

MATLAB小程序:关于MATLAB中整数浮点数\复数的运算(small MATLAB : MATLAB on integer float complex arithmetic)

采样定理的验证，即采样信号的频率大于等于原信号频率的两倍时才能准确的恢复原信号(Verification sampling theorem, the sampling frequency of the signal frequency is greater than or equal to twice the original signal in order to accurately restore the original signal)

很好的卡尔曼滤波器，应实现过了，程序中有解释说明部分，只须修改参数即可(Good Kalman filter should be realized, the program has some explanation, you can only modify the parameters)

卡尔曼滤波基础程序，关于运动模型的跟踪，很基础，适合初学者。(Kalman filter basic program.)

基于最小均方误差准则的LMS算法对淹没在噪声中的信号进行的有效的提取.(based on the minimum mean square error criteria LMS algorithm drowned in the noise signal the effective extraction.)
