Description
Summary:We propose a new adaptive admission control scheme for multiuser OFDMA systems to allocate wireless resource with low complexity. In this adaptive admission control scheme, the number of users is estimated adaptively by using the required data rate, bit error rate (BER) and average channel gain of each user at frame by frame. The resource allocation complexity becomes lower since the proposed method estimates the approximate number of users to be supported and reduce the repetition of actual resource allocation. Simulation result shows that the proposed method has high accuracy when ACG (Adaptive Craving Greedy) is used as the resource allocation scheme.
