Abstract

Multicarrier transmission schemes have been widely adopted in wireless communication systems. Multiple users can share a multicarrier channel using multiple access mechanisms such as OFDMA. This paper studies some unique features of multicarrier transmission and how these effect the performance of a multiple access system. Algorithms are derived for resource allocation in static and dynamic OFDMA systems. Numerical results demonstrate that the proposed approach (algorithm) offer comparable performance with existing algorithms. In this paper, a new algorithm for subcarrier allocation (Hybrid BABS) for the downlink of multiuser OFDM transmission is presented. The proposed algorithm is more stable and it offers a lower complexity and better performance than previous existing algorithms.
