Interleavers for IDMA Technology: A Comparison Survey

This paper provides a review on the IDMA (Interleave Division Multiple Access) technology in communication system based on different types of interleavers. IDMA employs interleavers as the only means in order to distinguish the users. This paper provides a comprehensive study of IDMA technique with orthogonal interleavers, power interleavers, prime interleavers, tree based interleavers and random interleavers. In this paper, the authors compare different interleavers based on computational complexity, bit error rate and memory requirement. The few basic requirements for future wireless 4G systems includes low receiver cost, decentralized (i.e. asynchronous) control, simple treatment of ISI, cross cell interference mitigation, diversity against fading, power efficiency (long battery life), multimedia services, high user number, high throughput and high spectral efficiency.
