Abstract

Applying smart antennas to an OFDMA system is investigated. A simple resource allocation scheme for array-antenna based OFDMA systems is proposed. The resource allocation algorithm is applied to the pilot data when no beam is formed and channel estimation in frequency-domain is implemented. After piloting, a beam is formed for each user to enhance the performance of the system. Simulations based on the SUI channel model according to the standard of IEEE 802.16e WMAN are carried out to examine the performance of the proposed approach.
