Abstract:
Relay based communication has gained considerable
importance in the recent years. In this paper we find the end-toend
statistics of a two hop non-regenerative relay branch, each hop
being Nakagami-m faded. Closed form expressions for the probability
density functions of the signal envelope at the output of a selection
combiner and a maximal ratio combiner at the destination node are
also derived and analytical formulations are verified through computer
simulation. These density functions are useful in evaluating the
system performance in terms of bit error rate and outage probability.
