| Abstract: | Wireless communication systems are subject to short term and long term fading of the
channel. Instead of the commonly used Nakagami-lognormal model to account for the
conditions existing in these shadowed fading channels, a compound probability density
function (pdf) model is used to evaluate the performance of wireless systems. While the
Nakagami-lognormal lacks a closed form solution to the pdf of the received power in
shadowed fading channels, the compound pdf has an analytical expression for the pdf of
the received signal power. The synergy between these two models for the analysis of
wireless systems is explored by calculating the bit error rate in a DPSK modem as well as
the outage probability in a wireless system in a shadowed fading channel. This is
followed by the computation of the outage probability in the general case where both the
desired and cochannels are subject to shadowing and fading. The analyses were carried
out for both fixed number of cochannels and random number of cochannels. Results
demonstrate the usefulness of the compound pdf model for the performance analyses of
wireless systems in shadowed fading channels. |
