用MATLAB的SIMULINK做的BPSK调制仿真(Using MATLAB-SIMULINK simulation do BPSK modulation)

说明：  有关自动控制方面的惯性环节响应，matlab仿真程序(control of the inertial response link, Matlab simulation program)

若干节点潮流计算，电气工程专业电力系统专业重要计算算法。(Number of nodes flow calculation, electrical engineering professional power system the important calculation algorithm.)

Creat a signal with white noise

说明：  这个程序可以用来小波和很重大很彪悍很特殊讨厌这个设置只想下载一个小程序(This procedure can be used to wavelet material is sturdy and very very special hate this setting only want to download a small program)

In mathematics, the method of steepest descent or stationary phase method or saddle-point method is an extension of Laplace s method for approximating an integral, where one deforms a contour integral in the complex plane to pass near a stationary point (saddle point), in roughly the direction of steepest descent or stationary phase.

这本书详细地描述了UML统一建模语言，对使用者有很好的导向作用 (This book describes in detail the UML Unified Modeling Language, the user has a good guide)

Most of the algorithms presented in the literature and in this chapter are basically intuitive and are intended to work with ECG signals in accepted clinical conditions, i.e. SNR higher than 18 dB.
