文章讲述了现在韩国的频谱政策和动态频谱接入技术。过去韩国的频谱管理政策需要特权，并且只有一小部分频谱可以公用。随着无线技术的发展，现在，韩国政府，使用了机遇动态频谱接入的新型频谱策略，例如LBT技术用于REID，UWB和FACS等。MIC还考虑如何在DTV过渡完成后，重新分配频谱。新型的无线电技术如认知无线电和SDR将在UHF边带中应用新的服务。MIC试图用一用有效地方式开放频谱并接受新技术用于频谱策略中。(In this paper, we introduce spectrum policies and dynamic spectrum access technologies in Korea. In the past, Korea spectrum management was the command and control with exclusive usage rights and small portions of spectrum commons bands. With the development of the radio technologies, Recently, Korea government, MIC(ministry of information and com- munication), has been adopting new spectrum policies based on dynamic spectrum access technology such as LBT(Listen Before Talk) for RFID, UWB, and FACS(Flexible Access Common Spectrum) etc. MIC is also considering spectrum reallocation of digital dividend bands after DTV transition. New radio techniques such as cognitive radio and SDR will be applied to new services in this UHF band. MIC is trying to open the radio spectrum in an efficient way and adopt new technology into spectrum policy. Thus MIC is extending the open spectrum such as spectrum commons and spectrum liberalization bands. )

说明：  这种是一个评价方法 可以用来评价较为客观公正(This is an evaluation method, which can be used for evaluation, which is objective and fair)

说明：  故障诊断程序 支持向量机智能诊断 分为多个程序 数据输入、特征提取、功能函数等(Fault diagnosis procedure Intelligent diagnosis of support vector machine It is divided into several program data input, feature extraction, function function, etc)

用 LDPC 解码法，对原始信号通道的噪声进行评估，消去。具体原理可参照IEEE TCOM的论文。(Channel Noise Estimation or correlation estimation for distributed source coding Using Particle based Belief Propagation for LDPC decoding in AWGN and BSC models. This code is partially based on our published journal papers with some additional improvements. In this code, we removed the parameter lambda to reduce the number of free parameters. PBP estimator is distributed in the hope that is will be useful, but without any warranty. The codes have not been optimized, so the estimation speed may be slow. To use PBP estimator source code in your research, please cite our journal papers published in IEEE TCOM. )

说明：  小波神经网络实例，用一周的数据来预测未来一天的情况，使用MATLAB软件实现人工智能的方法。(A wavelet neural network example is used to predict the situation of the next day with one week's data. MATLAB software is used)

说明：  基于PCA人脸识别算法的研究，用matlab实现。(PCA-based face recognition algorithm using matlab to achieve.)

关于matlab的插值范例，简单描述了各种插值的效果对比(interpolation )

全相位FFT的matlab程序，结果很好，相位检测精度很高(all phase fft program in matlab, the out is good)

this is a sorce code matlab for interpolation data and create 2d graph
