Abstract

In this paper, we are analyzing a new Tree Based Interleaver (TBI) to generate user specific chip-level interleaving sequences for different users in an IDMA system, which reduces computational complexity with optimum memory requirement. This method of generation also solves the memory cost problem and reduces the amount of information exchange between mobile stations and base stations required to specify the interleaver. Simulation results are presented to show that the proposed interleavers perform well as compared to Random Interleavers in an IDMA system.
