Abstract

This paper is concerned with multi-user detection techniques for orthogonal frequency division multiplexing - interleave division multiple access (OFDM-IDMA) and IDMA with cyclic prefix (IDMACP). These two schemes have attractive features such as low-cost multi-user detection/equalization and flexible rate adaptation. We will show that significant performance improvement (i.e., the so-called multi-user gain) can be achieved by allowing concurrent multiple user transmission on common carries.
