Selection Diversity Receiver over Correlated Rayleigh Fading Channels in the Presence of Multiple Interferers
نویسندگان
چکیده
An approach to the performance analyses of signal-to-interference (SIR) based selection combining (SC) operating over the correlated Rayleigh fading channels experiencing an arbitrary number of correlated multiple, co-channel interferers is presented. General analysis of multibranch SC where each correlated branch experiences an arbitrary number of multiple correlated co-channel interferers. Infinite series expressions are obtained for the output SIR’s probability density function (PDF), cumulative distribution function (CDF) and an important measure of the system’s performances, the outage probability (OP). An average bit error probability (ABER) is efficiently evaluated for modulation schemes such as binary frequency-shift keying (BFSK) and binary differentially phase-shift keying (BDPSK).

Energy Detection of Unknown Signals over Composite multipath/shadowing Fading Channels
In this paper, the performance analysis of an energy detector is exploited over composite multipath/shadowing fading channels, which is modeled by Rayleigh-lognormal (RL) distribution. Based on an approximate channel model which was recently proposed by the author, the RL envelope probability density function (pdf) is approximated by a finite sum of weighted Rayleigh pdfs. Relying on this inter...

The average fade duration (AFD) finds diverse applications in evaluation and design of wireless communication systems. This quantity provides a dynamic representation of the channel and presents the average period of time for which signal stays below a predetermined threshold level.
