Abstract
In this paper, we consider a dual-hop multiple-relay network with hybrid relay selection (HRS). The analytical symbol error rate (SER) is derived, and the optimum power allocation (OPA) methods are presented based on the closed-form and simplified SER expressions. The analytical results are verified by computer simulations. Simulation results also show that the SER performance of the HRS scheme is effectively improved by using power allocation, especially as the number of relays increases.
