I. INTRODUCTION
The increased demand for multimedia applications promotes
the investigation on multiple access (MA) technologies
that can support high date rates, various quality of services
(QoSs) in future broadband wireless networks. Latest investigations
have demonstrated the interleave-division multipleaccess
(IDMA) technology as a potential solution to highdata-
rate/multi-rate applications over fading channels [1]–[5].
In this paper, we investigate the QoS issues in IDMA-based
multi-service wireless networks. As the background of our
work, here we first elaborate on the concept of IDMA.
sir,
ReplyDeletei'm just trying to study idma. i got some doubts
1)whats the differnce between scrambling and interleaving
2)what are the affects of both both coding and spreading on bandwidth?( both of them increase the bandwidth there is a distinction i GUESS) WHAT IS THAT. is that related to shannon bandwidth ?
3)how can chip level inter leaving solve the problem of code gain ?
i really expect one of you to clarify at least some of my doubts?
i gone through a lot of ieee papers about idma. but u know these papers are hard to understand
