The performance of a dual-hop decode-and-forward relay system is investigated in the mixed fading channels. Firstly, under optimal relay selection, the closed-form expressions for the outage probability, average symbol error probability and asymptotic average symbol error probability are derived. Secondly, an optimizing power allocation method is derived based on the asymptotic average symbol error probability. Monte Carlo simulations validate the analysis and the simulation results show that the system performance under optimal power allocation is better that under equal power allocation. %K Mobile communication %K Decode-and-forward %K Outage probability %K Symbol error probability
