In wireless communication, regarding all the multiple access schemes, fading is referred to be major problem in multipath environment. Recently, IDMA scheme has attracted much attention of the researchers all over world as a potential candidate for future generation wireless communication systems. This scheme has also been victim of fading phenomena during communication process. In this paper, the...
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...
Power allocation with unequal strategy, is a technique to further enhance system performance in multiple access schemes. This paper is basically related with the performance enhancement of iterative IDMA systems using unequal optimum power allocation algorithm. Here, we compare the performance of coded and uncoded IDMA system with random interleaver & tree based interleaver. The simulation results...
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...
