Comparative Analysis of FLR Approach Based Inverse Tree and Modern Fisher-Yates Algorithm Based Random Interleavers for IDMA Systems

`Interleave-division multiple-access' (IDMA) systems are interleaver centric advanced multiple access systems for modern day's communication. These systems can effectively combat with multiuser and multiple access interferences. In recent years, several interleaving approaches compatible with IDMA system have been designed and analyzed. In this paper, two of such recently developed interleaver generation techniques namely flip left-right approach based inverse tree interleaving (FLRITI) and modern Fisher-Yates algorithm based random interleaving (MFYI) techniques have been reviewed and compared for IDMA systems. `Bit error rate (BER), computation complexity, computation delay and memory requirements are the main parameters used in this performance comparison.
