Application of Diversity Techniques for Multi User IDMA Communication System

Abstract

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 (IDMA) scheme. The approach explains receiver diversity as well as transmits diversity analysis as 1:2 and 2:1 antenna system in fading environment, no. of antennas can be increased to improve diversity order. Random interleaver as well tree based interleaver has been taken for study. Significant improvements in performance of IDMA communication is observed with application of diversity techniques.
