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, random interleaver as well tree based interleaver has been taken for study. The simulation results demonstrates that in both environments, tree based interleavers outperforms the random interleaver. Significant improvements in performance of IDMA scheme is observed with MRC diversity technique.
