是Matlab图像处理的原程序代码，适合初学者使用。(Matlab image processing is the original code, suitable for beginners.)

说明：  摘要：用MATLAB对基带数据传输解调检测进行仿真，推导不同先验概率下，接收端最小错误的判决门限。仿真不同先验概率下的误码性能，二进制与多进制的误码性能比较，码间串扰对误码性能的影响，及频偏对串行通信误码率的影响。 关键词：MATLAB，基带传输，检测，判决门限 (Abstract: Using MATLAB for baseband demodulation simulation data derived under different prior probability, the receiver decision threshold minimum error. Simulation under different prior probability of error performance, binary and multi-bit error performance of binary comparison ISI on the BER performance, and the offset of the serial communication error rate. Keywords: MATLAB, baseband transmission, detection, decision threshold)

所给程序中，先给出一副原始图像，在其中添加椒盐噪声，然后用几种方法进行平滑滤波，包括邻域均值法，邻域中值滤波和K邻域均值滤波，其中的K邻域均值滤波所选掩膜为3*3，K值取5，图片选用board.ti。(Given program, the first is given an original image, in which the added salt & pepper noise, and then use several methods of smoothing, including the neighborhood average method, o-field value filtering and K neighborhood mean filter, where K o domain mean filter mask for the selected 3* 3, K value of taking five, picture selection board.ti.)

说明：  对数字信号进行BFSK调制，然后通过高斯白噪声信号后，检测其误码率！(The program s function is to modulate a signal with BFSK,then let the signal go pass a channel of guassian white nosie.At last,The program detects the BER of the signal.)
