Complex networks have some common basic model, such as random graph, WS small-world networks, NW small-world networks and scale-free BA network, the program generated from the mechanism of these networks to generate the complex network model and analysis its basic nature, such as the average path length.

M=4的PSK通信系统进行蒙特卡罗仿真 仿真BPSK和4PSK调制信号在高斯信道下的性能，并与理论分析结果相比。 (1) 画出两条性能曲线，一条是根据理论平均错误概率画出，另一条是仿真曲线； (2) 程序的基本流程：信源产生信息比特、调制、将调制信号送入信道(产生高斯白噪声的程序)、接收端检测、将检测结果与信源原始信息比较计算误符号率和误比特率； (3) 在给定信噪比下，第二步需多次重复，以得到一个平均错误概率； (4) 信噪比范围：BPSK(0dB – 10dB)，4PSK(0dB-14dB)，间隔是1dB 也可在BER=10-6左右终止。 (5) 信噪比计算 SNR=10log(Es/N0)=10log(REb/N0).

能使桌面上不停的换色.请先生成EXE再运行不然会出错。(Enable non-stop for the desktop color. Please re-run the EXE generated will not go wrong.)

Its a great tool to getting started with the new John Carter software for source code.

利用matlab生成word和excel文件的源码已经实例数据。源自谢中华老师的教材。(Using matlab to generate word and excel file data source is instantiated. Xie Zhonghua teachers from teaching.)

录制一段个人自己的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；给定滤波器的性能指标，采用窗函数法和双线性变换设计滤波器，并画出滤波器的频率响应；然后用自己设计的滤波器对采集的信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，分析信号的变化；回放语音信号；最后，设计一个信号处理系统界面。(Record a person s own voice signal, and recording the signal sampling draw sample after the speech signal time-domain waveform and frequency spectrum given filter performance indicators, using a window function method and the bilinear transform filter design and draw the frequency response filter then use the filter of their own design for the signal acquisition filtering, after filtering the signal to draw the time-domain waveform and spectrum, and filtering of signals before and after contrast, analysis of signal changes playback of voice signal Finally, the design of a signal processing system interface.)
