Description: 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. Platform: |

Description: Today’s wireless networks are characterized by fixed spectrum assignment policy. The limited available spectrum and the inefficiency in the spectrum usage necessitate a new communication paradigm to exploit the existing wireless spectrum opportunistically. Cognitive radio is a paradigm for wireless communication in which either a network or a wireless node changes its transmission or reception parameters to communicate efficiently avoiding interference with licensed or unlicensed users. It can capture best available spectrum to meet user communication requirements (spectrum management). Platform: |

In addition, it is the spectrum that disturbs the level of management caused by primary users (PUs). Remote sensing provides awareness of the radio operating environment. Cognitive stations can then adapt to its parameters such as carrier frequency power and waveform dynamics to provide the best service available to connect to meet user constraints on interference requirements. In wireless communication systems, we usually have some primary users who have knowledge of the waveform and the spectrum of the signal of the structure or statistic properties. This knowledge may be related to the modulation scheme, symbol or chip signal, channel speed.) Platform: |

Description: 博弈论应用于认知无线电的有价值的文章，可供初学者学习。(Various spectrum management schemes have been proposed in recent years to improve the spectrum utilization in cognitive radio networks. However, few of them have considered the existence of cognitive attackers who can adapt their attacking strategy to the time-varying spectrum environment and the secondary users' strategy. In this paper, we investigate the security mechanism when secondary users are facing the jamming attack, and propose a stochastic game framework for anti-jamming defense. At each stage of the game, secondary users observe the spectrum availability, the channel quality, and the attackers' strategy from the status of jammed channels. According to this observation, they will decide how many channels they should reserve for transmitting control and data messages and how to switch between the) Platform: |
