Mobile Communication Systems in the Presence of Fading/Shadowing, Noise and Interference

by Petros S. Bithas, Athanasios A. Rontogiannis
"... Abstract—In this paper, the effects of interference on composite fading environments, where multipath fading coexists with shad-owing, are investigated. Based on some mathematical convenient expressions for the sum of squared K-distributed random vari-ables, which are derived for the first time, imp ..."

of the average bit error probability (ABEP) and the outage probability (OP), of such systems operating over composite fading environ-ments. A high SNR analysis is also presented for the OP and the ABEP, giving a clear physical insight of the system’s performance in terms of the diversity and coding gains

Error performance of ultrawideband systems in a Poisson field of narrowband interferers

by Moe Z. Win, Pedro C. Pinto, Andrea Giorgetti, Marco Chiani - in Proc. IEEE Int. Symp. on Spread Spectrum Techniques & Applications , 2006
"... Abstract—This paper presents a mathematical model for ultrawideband (UWB) communication in the presence of nar-rowband (NB) interference. In particular, we derive a closed-form expression for the bit error probability of a UWB link, when a Rake receiver is employed and the NB interferers are approxi ..."

We consider a realistic scenario of slowly-moving, asynchronous nodes in a wireless environment subject to path loss, log-normal shadowing

Outage Probability in Multiple Access Packet Radio Networks in the Presence of Fading

by Michele Zorzi, Student Member, Silvano Pupolin, Senior Member - IEEE Trans. Veh. Tech , 1994
"... The outage probability in a mobile communications environment, where the interferers are randomly distributed on the ground, taking into account the background noise, the co-channel interference and the random effects of propagation (log-normal shadowing and Rayleigh fading), is evaluated. Although ..."

BER Performance Evaluation of GMSK for Fading Mobile Channels

by Gejo George, Srija Unnikrishnan
"... Abstract — Digital modulation plays a significant role in efficient wireless communication. It allows the transmission of digital data via air on high frequency carrier waves. The worst case communication channel is usually in the urban environment where there are many obstacles. Due to the obstacle ..."
