Aloha

通过这个算法可以确定BP神经网络中隐层最优神经元个数(Determine the BP neural network hidden layer neuron number of optimal)

利用matlab的m函数和simulink达到题目中的要求(Use matlab m-function and simulink meet the requirements of the title)

说明：  分形彩图的C或者matlab的源代，可执行的绘制彩色分型算法图形的C或者matlab的源代码，需要3段，也就是3张图。图片尽可能好看(The fractal color of C or matlab source code, executable drawing color genotyping algorithm graph C or matlab source code need 3 paragraphs 3 in Fig. Picture as possible look good)

加权零阶域算法，预测的相对误差大概能控制在5 以内。用于上证指数的预测。(Weighted zero-order domain algorithm to predict the relative error can be controlled within about 5 . For the Shanghai index forecast.)

用matlab实现短时能量和过零率的端点检测，并显示波形(using Matlab to achieve short-term energy and zero rate of endpoint detection and waveform display)

说明：  时间序列分析中随机微分方程方面的实现,在matlab环境下实现的代码(stochastic differential equations )

BPSK调制解调直接序列扩频系统源代码(白噪声及瑞利衰落误码率比较)(BPSK receiver simulation using Spread Spectrum Techniques )

用于数字水印的添加，可以根据幅度的大小自动调节水印幅度，用直扩2psk实现(Used to add a digital watermark, the watermark can be automatically adjusted according to the size of the magnitude of the amplitude with DSSS 2psk achieve)

msk的调制解调，包含调制解调过程中信号、功率谱的图、调制后的对比图(msk modulation and demodulation process, including modulation and demodulation signal, the power spectrum of FIG modulated contrast FIG.)
