This paper is concerned with the performance improvement of iterative Interleave-Division Multiple-Access (IDMA) scheme based receivers using optimum power allocation algorithm using tree based interleavers (TBI). Based on the optimized power allocation technique, we compare the performance of IDMA receiver with random interleaver, power interleaver, and tree based interleaver. The simulation results...
In wireless communication, fading problem is mitigated with help of diversity techniques. This paper presents Maximal Ratio Combining (MRC) diversity approach to uproot the fading problem in interleave-division multiple-access (EDMA) scheme. The approach explains maximal ratio combining diversity technique, with one transmit and two received antennas in low rate coded environment. In the simulations,...
This paper is concerned with the performance enhancement of IDMA systems using optimum power allocation algorithm. Based on the optimized power allocation technique we compare the performance of coded and uncoded IDMA system with random interleaver & tree based interleaver. The simulation results demonstrate the superior performance of tree based interleaver in comparison to random interleavers.
Here, we propose a novel tree based interleaver (TBI) for generating user specific chip-level interleaving sequences for various users in an IDMA system, which reduces computational complexity drastically. This interleaver 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...
