Abstract :
In this paper, we evaluate the voice traffic performance of an OFDM (Orthogonal Frequency Division Multiplexing) wireless access system. We propose an algorithm for serving handover calls with higher priority than new calls, considering different AMC (adaptive modulation and coding) modes. The purpose is to efficiently utilize the scarce radio resources in order to improve the system performance.
