Abstract

Fourth generation (4G) communication systems require bandwidth efficiency and low complexity receivers to accommodate high data rates and large number of users per cell. This paper provides an introduction to a novel approach for uplink scenario in 4G mobile communication called multi-carrier interleave-division multiple-access (MC-IDMA). In this paper basic principles of interleave division multiple access (IDMA), orthogonal frequency division multiple access (OFDMA), and MC-IDMA are outlined. Comparisons are carried out between IDMA, MC-IDMA and multi-carrier code division multiple-access (MC-CDMA). The advantages of MC-IDMA over its competitive techniques are demonstrated. It is shown that MC-IDMA can be leading candidate for 4G mobile systems with its attractive advantages such as flexible rate adaptation, frequency diversity and multi user gain.
