Abstract: Smart antennas are capable of offering major contribution in improving system performance of orthogonal frequency division multiplexing (OFDM) systems. The OFDM is an air-link technology required for future wireless communication applications to address the technological challenges in fulfilling users demand. The adaptive resource allocation techniques in OFDM systems using smart antennas is an optimistic approach showing light towards developing various methods to improve spectral efficiency with required quality of service (QoS). However, fully adaptive techniques increase the challenges in designing the physical layer with minimum complexity. Now, the challenge is to investigate the possibility of achieving satisfactory system performance without increasing complexity at MAC layer of next generation OFDM systems. In this paper, methodology of designing a hybrid smart antenna system is proposed to achieve required QoS with minimum system complexity.
