PERFORMANCE OF IDMA WITH PRIME INTERLEAVER BY USING SEMI-BLIND DETECTION TECHNIQUE IN WIRELESS COMMUNICATION SYSTEM

Farheen begum

Abstract


This paper provides a review on the IDMA (Interleave Division Multiple Access) technology in wireless communication system based on interleaver. It provides comprehensive study of IDMA technique with prime interleaver. In this paper, channel estimation techniques for iterative receiver are discussed for IDMA system. Semi-Blind techniques are considered .In this paper, IDMA technique is proposed in AWGN channel. IDMA is a multi- user scheme in which chip interleavers are the only means of user separation. The receiver involves a chip-by-chip iterative multi-user detection. The IDMA performance in terms of bit error rate, bandwidth efficiency and complexity reduction is discussed. In proposed scheme an IDMA system with semi-blind detection technique that simulate in AWGN channel environments by using Prime Interleaver. Thus, it promises a good performance compared with the IDMA when a priori information is perfectly estimated. 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.
