The Slashed‐Rayleigh Fading Channel Distribution

open access: yesMathematical Problems in Engineering, 2019
We propose an alternative distribution for modelling fading‐shadowing wireless channels. This distribution presents certain advantages over the Rayleigh‐lognormal distribution and the K distribution and has proved useful in the setting described. We obtain closed‐form expressions for the average channel capacity and for the average bit error rate of ...

Performance analysis of energy detection over hyper-Rayleigh fading channels

open access: yesThe Journal of Engineering, 2015
This study investigates the performance of energy detection (ED)-based spectrum sensing over two-wave with diffused power (TWDP) fading channels, which have been found to provide accurate characterisation for a variety of fading conditions. A closed-form

MLSE receiver for the dispersive Rayleigh fading channel [PDF]

open access: yesProceedings of ICC'97 - International Conference on Communications, 2002
A maximum likelihood sequence estimator for the dispersive Rayleigh fading channel is developed. Following [1, 2], the MLSE uses a Kalman based channel estimator to acquire the channel parameters necessary to formulate the maximum likelihood metric. However, unlike the MLSE receiver presented in [1, 2], the proposed receiver uses the f-power series ...

Analysis of transmit-receive diversity in Rayleigh fading [PDF]

open access: yesGLOBECOM'01. IEEE Global Telecommunications Conference (Cat. No.01CH37270), 2002
We analyze the error performance of a wireless communication system employing transmit-receive diversity in Rayleigh fading. By focusing on the complex Gaussian statistics of the independent and identically distributed entries of the channel matrix, we derive a formula for the characteristic function (c.f.) of the maximum output signal-to-noise ratio ...

On routing in random Rayleigh fading networks [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2005
This paper addresses the routing problem for large wireless networks of randomly distributed nodes with Rayleigh fading channels. First, we establish that the distances between neighboring nodes in a Poisson point process follow a generalized Rayleigh distribution.

Adaptive modulation in a slow Rayleigh fading channel [PDF]

open access: yesProceedings of PIMRC '96 - 7th International Symposium on Personal, Indoor, and Mobile Communications, 2002
A novel, uneven protection phase shift keying technique is proposed for the encoding of the required modulation scheme in an adaptive modem arrangement, which exhibits an improved performance in comparison to previously proposed schemes. The performance is derived numerically and a system dependent optimisation is presented.

Compensating for Channel Fading in DS-CDMA Communication Systems Employing ICA Neural Network Detectors [PDF]

open access: yesJournal of Systemics, Cybernetics and Informatics, 2005
In this paper we examine the impact of channel fading on the bit error rate of a DS-CDMA communication system. The system employs detectors that incorporate neural networks effecting methods of independent component analysis (ICA), subspace estimation of
