一维光子晶体透射率与折射率差值的关系示意图，总体上来说，不同介质的介电常数差别越大，带隙的宽度也越宽。(The diagram of photonic crystal transmittance of one-dimensional and refractive index difference)

这是一个在matlab下模拟ask 和 bpsk调制和解调的代码(this is a file wirtten by Matlab, to explain the ASK and BPSK in a correctly way )

压缩文件中是Maple程序设计.doc，总结了一些简单的maple软件的用法(Compressed file is Maple programming. Doc, summarizes some simple maple software usage)

里面是Matlab宝典丛书的源代码，应该来说对于学习Matlab的人员是很有用的(Matlab Books Collection which is the source, should be run for staff learning Matlab is useful)

利用mcra的方法对噪声功率谱估计达到语音增强的目的(estimate the spectrum of the noise in order to enhance the SNR of the speech)

基于微粒群模型的无线传感器网络节点部署研究(Research on the deployment of wireless sensor network node based on particle swarm optimization model)

采用极限学习机即（ELM）进行回归和预测的MATLAB代码, 亲测可用，只需要替换自己的数据即可.(Extreme learning machine (ELM) is used for regression and prediction with MATLAB code. You need only use your own data to represent the data in the code.)

在分析高效宽频带变频系统的基础上提出一种可以把变频部分与多种调制方式灵活结合在一起的方法，并以QAM调制为例，给出具体算法．分析结果表明，该方法降低了对处理速率的要求，提高了处理能力(In order to design an efficient and flexible DDC／DUC system，this paper combined the signal processing of DDC／DUC with QAM system and presented a new method based on the analysis of this efficient broadband DDC／DUC system．QAM modulation was taken for example，and a detailed algorithm of a channel system with 0～30 MHz and 60 channels QAM was presented)
