IDMA-Based on Chaotic Tent Map Interleaver

Interleave Division Multiple Access (IDMA) is a popular multiple access scheme and can be considered as one of the powerful NOMA (non-orthogonal multiple access) technique for 5G communication requirements. In IDMA, the interleaver plays a vital role as the means to distinguish the different users in the channel. An "efficient" Interleaver in IDMA scheme must be simple and non-colloidal in nature. So, in this paper, the analysis and designing of a new Tent map based Interleaver (TMI) matrix is proposed for IDMA system. Further, the simulation experiments have been performed among TMI and other famous interleaver designs to validate the bit error rate performance of "TMI". The simulation results explain that Tent map based chaotic (TMI) interleaver performs better in terms of bit error rate and computational complexity.
