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.
