Description: 这个程序可以计算给定点处的小区信号范围覆盖。-is program computes a map of visibility from a selected point on a topography. It has been written to help the search for radio relay best location. Because it considers only direct line of sight, it gives a good estimation for possible radio link for short distances only (less than 10 km), neglecting curvature of the Earth, Fresnel zone and atmospheric refraction on radio waves propagation. The program computes the relative elevation angle of the mask for each point (the angle is null or negative if the point is visible).
The function needs a digital elevation model Z and associated (X,Y) vectors or matrices of coordinates (same unit as Z), position of the point (X0,Y0), the antenna height H0 (for instance 4 m), and the hypothetic antenna height Ha on each topography points (for instance 3 m). When no output argument is given, the function plots a map of the results (color map of mask angles, and blank for visible points, see example screenshot).

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: 本书是关于无线衰落信道方面的一本好书，书中内含MATLAB代码！
-All relevant components of a mobile radio system, from digital modulation techniques over channel coding through to network aspects, are determined by the propagation characteristics of the channel. Therefore, a precise knowledge of mobile radio channels is crucial for the development, evaluation and test of current and future mobile radio communication systems. This volume deals with the modelling, analysis, and simulation of mobile fading channels and provides a fundamental understanding of many issues that are currently being investigated in the area of mobile fading channel modelling. The author strongly emphasises the detailed derivation of the presented channel models and conveys a high degree of mathematical unity to the reader.
Introduces the fundamentals of stochastic and deterministic channel models
