the comb pilot aided channel estimation in ofdm modulation is considered. the power of pilot subchannels is under the control. The data experience frequency selective channel then the AWGN noise is added to make the situation worse. The bit error rate is ploted versus SNR.

源码，非常实用，里外都是经过上机调试的源码，可以直接使用！(Source, very useful, both inside and outside the machine through the source debugger, you can directly use!)

说明：  基于agent图的脆性仿真程序，研究对象是船舶电力系统(Agent-based simulation program brittle graphs, study the ship power system)

these codes are used to sharpen the images , and detect edges of images using edge operators

说明：  噪声对消算法； 消除信号中得噪声； 多传感器处理方法；(Noise cancellation algorithm; Eliminate noise in the signal; Multi-sensor processing method;)
