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.
