Abstract

Orthogonal frequency division multiplexing (OFDM) is emerging as a key modulation scheme for future high speed packets based wireless transmission systems. In a wireless multiuser network system, when an opportunistic scheduling is employed in the OFDM system with adaptive modulation, it may encounter implementation problems due to the need for a large amount of channel information. In this paper, we adopt an idea that we proposed in [1] called discrete rate switch-based multi-user diversity system (DSMUDiv) and combine it with the idea of Enhanced Equal Access scheduling policy that was proposed in [2] to reduces the feedback load and guarantee high probability of access for each user while maintaining most of the performance of opportunistic scheduling. We present an analytical analysis of the feedback load, spectral efficiency and probability of access of the proposed scheme.
