Implementation of Interleave Division Multiple Access (IDMA) with Multiple Users in Wireless Communication System

Abstract

This paper provides a review on the IDMA (Interleave Division Multiple Access) technology in wireless communication system based on Interleaver. In this paper, IDMA technique is proposed in AWGN channel. IDMA is a multiuser scheme in which chip Interleavers are the only means of user separation. The receiver involves a chip-by-chip iterative multiuser detection. The IDMA performance in terms of bit error rate, bandwidth efficiency and complexity reduction is discussed. However, we observe that during iterative process, the IDMA output performs well with ISI Cancellation when numbers of users increases. Indeed, the increase in the number of users requires the independent processing of MAI and ISI that is carried out in IDMA.
