Optical Interleave Division Multiple Access (OIDMA) System-A Review

In Interleave Division Multiple Access (IDMA), users are assigned with specific inter-leavers instead of PN-sequences as in case of Code Division Multiple Access (CDMA) systems to differentiate amongst users. The scheme considered is a special case of CDMA in which bandwidth expansion is entirely performed by low-rate coding. An inter-leaver-based multiple access scheme gives high spectral efficiency, improved performance and low receiver complexity. IDMA scheme shows an inter-leaver as the only means to distinguish the signals amongst users, and hence called as Interleave Division Multiple Access (IDMA).
