PolicyandTechnologyofDynamicinKorea
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. )

采用多天线的认知无线电系统相对于单天线认知无线电系统,既有传统的资源(频域,时域,码域),又有空域资源。本文研究基于博弈论的有限反馈认知MIMO系统的资源分配,涉及发射功率、空域(采用波束成形)和反馈速率等资源的分配。利用有限的反馈信道反馈量化的信道状态信息(CSI),基于量化CSI,本文主要研究联合功率分配与波束成形优化、次用户(认知用户或非授权用户)反馈速率控制、联合功率分配与反馈速率控制等相关资源分配问题。(Multi-antenna cognitive radio system with respect to a single antenna cognitive radio systems, both traditional resource (frequency domain, time domain, code domain), there airspace resources. In this paper, a limited resource allocation game theory of cognitive MIMO system based on feedback, involving the launch distribution power, airspace (using beam-forming) and feedback rate and other resources. With limited feedback channel feedback quantized channel state information (CSI), based on quantified CSI, this paper studies the joint power allocation and beamforming optimization, secondary users (cognitive user or unauthorized user) feedback rate control, joint power allocation and feedback rate control and other issues related to resource allocation.)

lyapack
LYAPACK is a MATLAB toolbox for the solution of certain large scale problems in control theory, which are closely related to Lyapunov equations. In contrast to the lyap and dlyap command in the MATLAB Control toolbox it uses iterative algorithms and is intended for large, sparse problems.
