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. )

二维MUSIC算法，用于DOA估计，写论文必用(MUSIC，which is used to DOA, is necessary to write papers.)

Abstract—In this paper, a new lossy technique based on wavelet transform for compression of breast ultrasound images is presented. The experiments are performed on 16 different wavelet functions and the quality of reconstructed images is evaluated by using Compression Ratio (CR), Normalized Mean Square Error (NMSE), Normalized Absolute Error (NAE), and Peak Signal to Noise Ratio (PSNR) criterion. An ultrasonographer performed the subjective assessment. This study shows that among the utilized wavelets,

说明：  一、 实验目的 在计算机上用迭代法求非线性方程地f(x)=0的根。 二、 实验平台 操作系统：Microsoft Windows Vista SP1 数学软件：Matlab7.0.0.19920(R14) (First, the experiment was on the computer using iteration method to nonlinear equations f (x) = 0 root. Second, experimental platform, operating system: Microsoft Windows Vista SP1 mathematical software: Matlab7.0.0.19920 (R14))

这是我收集到的最全的关于matlab程序实例应用，尤其对于学习数学的同学最有帮助。很牛的，有需要的我还可以再传一些。免费为有需求的人写程序。(This is my collection of the most complete examples of the application of Matlab procedures, especially for students studying mathematics most helpful. Niu is, I need the re-some can. Free for the demand for a written procedure.)
