Relay based communication has gained considerable importance in the recent years. In this paper we find the endtoend statistics of a two hop nonregenerative relay branch, each hop being Nakagamim 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.
