The horse moves on a chessboard so that the whole house of sacrifice and not refuse any house twice. be fun.

说明：  要：分析和研究了授权用户和认知用户共享频谱的一种算法的性能。 针对阴影效应或信道深衰落时，单用户频谱感知算法无法识别是频带未被 使用还是信道处于深衰落的情况，在频谱感知功率控制算法上进行了改进， 以克服这种算法的不足。改进后的算法能有效地控制认知用户的发射功率， 避免对授权用户产生有害的干扰。仿真结果表明改(To: analysis and research of the authorized users to share spectrum users and a cognitive performance of the algorithm. For the shadow effect or deep fading channel, the single-user spectrum sensing algorithm can not identify a band or a channel has not been used in the case of deep fading, the spectrum sensing power control algorithm has been improved on, to overcome the deficiencies of this method. The improved algorithm can effectively control the cognitive user' s transmit power, to avoid harmful interference with authorized users. Simulation results show that the change)

说明：  用与matlab的fsk调制的信号的波形的代码，可以实现仿真(it is fsk)

有限差分波场模拟利用声波方程进行有限差分正演模拟。(the simulation of acoustic wave.using the acoustic wave equation. in the program i deal with the edge and the result.)

Decimation reduces the original sampling rate for a sequence to a lower rate, the opposite of interpolation. The decimation process filters the input data with a lowpass filter and then resamples the resulting smoothed signal at a lower rate.

BP Network ，实现对BP网络的编程，采用matlab实现，基本的BP网络(BP network )
