Micro-Characterization of Wireless Channels
2004The previous chapter concentrated on estimation of the mean or median signal strength for a given transmitter and receiver geometry characterized by a certain terrain definition in a coverage area. The concept of statistical signal coverage was also presented.

Characterizing Turbulent Channel Flow
1986We discuss different methods of characterizing turbulent channel flow in terms of “the number of independent degrees of freedom”. These methods all suggest that the dimension of this system is greater than 10.

Characterizing network covert storage channels
[Proceedings 1988] Fourth Aerospace Computer Security Applications, 2003A novel characterization is presented for covert channels in stand-alone systems. This characterization is used to examine the nature of covert channels in computer networks. Most network covert channels are shown to reduce to covert channels in standalone systems. The remaining identified network covert channels are identified to be examples of a more

This chapter provides an overview of the state of the art in channel characterization for power line communication (PLC). It sets the stage with an overview of basic power line topologies and characteristics of power line channels. The chapter discusses the channel models that fall into three main categories, namely deterministic, empirical and hybrid ...

Characterization of underwater acoustic channels
2015 International Conference on Applied and Theoretical Computing and Communication Technology (iCATccT), 2015Underwater communication is predominantly by acoustic waves. However the attenuation and delay associated with the acoustic channel limits the range and data rate supported. Channel simulators are required to support the deployment of expensive experimental setup which relies on the characterization of the underwater acoustic channel.

Channel characterization using bispectral analysis
Proceedings of the IEEE, 1988A method of characterizing a slowly varying linear channel in the presence of white Gaussian noise is proposed. The method uses a non-Gaussian probing signal and performs a bispectral analysis of the received signal. >

Characterization of wideband communication channels
IEEE Antennas and Propagation Society International Symposium. Transmitting Waves of Progress to the Next Millennium. 2000 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.00CH37118), 2002Summary form only given. The performance of wideband communication systems is heavily dependent on the characteristics of the channel. A set of second order statistics are defined for the characterization of the diversity of multipath fading channels.

Characterization of Digital Real Channels
IETE Journal of Research, 1973Errors encountered in digital transmission over real channels, like ionospheric and tropospheric scatter channels, are not independent in their occurrence but appear in clusters separated by error-free gaps. Characterization of these channels involves prediction of their basic behaviour for uncoded communication, and observation and modeling of the ...

GSCC Channel Characterization and Modelling
2017The aim of GSCC architecture is to facilitate a universal medium for varied signal transmission creating a cloud of communications. A power line communication (PLC) system coupled with the UCM as presented in the previous chapter allows the possibilities of not only utilizing the existing most pervasive and dense infrastructure, the electric power ...

UWB Spatia - Frequency Channel Characterization
2006 IEEE 63rd Vehicular Technology Conference, 2006This paper investigates the spatial-frequency channel characterization of Ultra-wideband (UWB) wireless communication systems. Firstly, a novel frequency dependent UWB channel model is constructed based on the theory of electro-magnetic diffraction mechanism, which causes the field strength to vary with the frequency in each multipath.
