基于FPGA的双口RAM实现及应用,对RAM有一个系统的介绍(The dual-port RAM-based FPGA Implementation and Application of RAM to have a systematic introduction)

采用加权网络中节点强度和权重都是幂率分布的模型，双向PCS控制仿真，能量熵的计算，重要参数的提取，基于人工神经网络的常用数字信号调制，应用小区域方差对比，程序简单。( Using weighted model nodes in the network strength and weight are power law distribution, Two-way PCS control simulation, Energy entropy calculation, Extract important parameters, The commonly used digital signal modulation based on artificial neural network, Application of small area variance comparison, simple procedures.)

是小学期课程设计的题目，小波包分析提取振动信号中的特征频率，音频信号通过LM386放大。( Is the topic of the elementary school stage curriculum design, Wavelet packet analysis to extract vibration signal characteristic frequency, LM386 audio signal amplification.)

宽带信号的空间谱估计以及信噪比等对信号估计的影响，才用聚焦矩阵的方法，采用的聚焦矩阵不同，性能也不同，这里是RSS算法(Spatial spectrum estimation of wideband signals and SNR of the estimated impact on the signal only with the focusing matrix method, using the focusing matrix of different, performance is different, here is the RSS algorithm)

一个包含常用特征提取方法的matlab工具包。内含 PCA, CCA, mnf, pls 、 KPCA, KCCA, kmnf, kpls 等算法的实现源码(a matlab toolkit Containing some common feature extraction methods . Containing PCA, CCA, mnf, pls, KPCA, KCCA, kmnf, kpls algorithm implementation source)

说明：  络检波法，也可以用同步解调法，现在我们来使用同步解调法，即将已调信号和一个与载波信号同频率的信号相乘，在通过一个理想低通滤波器就可以得到原始信号(Envelope detection method, you can also use synchronous demodulation method, and now we use synchronous demodulation method, is about modulated signal and a signal is multiplied with the same frequency of the carrier signal, through an ideal low-pass filter can get the original signal)

M AT L A B是一个可视化的计算程序，被广泛地使用于从个人计算机到超级计算机范围内 的各种计算机上。 M AT L A B包括命令控制、可编程，有上百个预先定义好的命令和函数。这些函数能通过 用户自定义函数进一步扩展。(M AT LAB is a visual computing program, and is widely used in a variety of computers from personal computers to supercomputers within. M AT LAB, including command and control, programmable, with hundreds of pre-defined commands and functions. Further expansion of these functions through user-defined functions.)
