RAYLEIGH FADING - SHADOWING OF OUTDOOR CHANNELS ANALYSIS BASED ON SNR-PDF MODEL
Mağallaẗ Al-kūfaẗ Al-handasiyyaẗ, 2019 The outdoor transmission channels condition in multiple wireless signals systems changes continuously due to signals transfer path characteristics. The path loss, multiple reflected rays Rayleigh fading and shadowing presents an important factor that ...

A Novel Method for Separating and Locating Multiple Partial Discharge Sources in a Substation
Sensors, 2017 To separate and locate multi-partial discharge (PD) sources in a substation, the use of spectrum differences of ultra-high frequency signals radiated from various sources as characteristic parameters has been previously reported.

Error Probability Analysis of a Composite Weibull/Log-Normal Fading Channel
Gazi Üniversitesi Fen Bilimleri Dergisi, 2019 In this study, error probability of a single-input single-output (SISO) system is investigated over a composite Weibull/log-normal fading channel. We aim to study a SISO system in the composite Weibull/log-normal composite fading model which is useful in

Finite Dimensional Infinite Constellations [PDF]
, 2011 In the setting of a Gaussian channel without power constraints, proposed by Poltyrev, the codewords are points in an n-dimensional Euclidean space (an infinite constellation) and the tradeoff between their density and the error probability is considered.

An Impossibility Result for High Dimensional Supervised Learning [PDF]
, 2013 We study high-dimensional asymptotic performance limits of binary supervised classification problems where the class conditional densities are Gaussian with unknown means and covariances and the number of signal dimensions scales faster than the number ...
