Abstract

Interleave Division Multiple Access (IDMA) is a multiuser scheme which enables user separation on the basis of interleavers. Interleaver design can allow the IDMA system to approach near Shannon limits of channel capacity. Interleaver combats against Intersymbol Interference (ISI), channel fading and all sorts of noises. In addition, interleavers provide security to the system users. Designing the random interleaver provides a solution for all impairments but they are generally considered computationally heavy. In this paper, an efficient approach has been developed for design of user specific random block interleavers. This design approach reduces the complexity for developing interleaving patterns and is computationally economical.
