An efficient downlink mapping algorithm for AMC mode in WiMAX systems

Abstract: This paper proposes an efficient downlink resource allocation scheme for Orthogonal Frequency Division Multiple Access based WiMAX systems using the Adaptive Modulation and Coding mode operation. Given a set of user requests, the proposed algorithm determines the modulation scheme and allocates a two-dimensional (time and frequency) burst to each user. It is known that finding the optimal solution for such a resource allocation problem is NP-complete. To reduce the computation complexity, this paper proposes a… Show more

“…To explore the multiuser gain under frequency selective channels, the AMC mode, where a subchannel consists of contiguous subcarriers, is often used to improve spectrum efficiency. The authors in [5] proposed a mapping algorithm considering the AMC mode and the rectangle constraint. However, [5] did not consider traffic differentiation in data mapping.…”
