A hybrid multiple access scheme: OFDMA-IDMA

Hongxia Bie, Zhisong Bie

Abstract

In this paper, we propose a hybrid multiple-access scheme which combines IDMA (interleave division multiple access) and OFDMA (orthogonal frequency division multiple access), named OFDMA-IDMA. The advantages of this scheme are analyzed and the probable application scenarios are discussed. A scheduling method for uplink based on convergence analysis techniques is also proposed to group users to share the same time-frequency resources effectively.
