Abstract :
We introduce an enhanced DQRUMA/MC-CDMA protocol for wireless packet networks. The original DQRUMA/MC-CDMA protocol may suffer severe code collisions due to a limited number of request codes. An enhanced DQRUMA/MC-CDMA protocol using minislots for request accesses is proposed to reduce request collisions. In the proposed protocol, request attempts can be transmitted concurrently with data packets of other calls. The performance of the proposed protocol is evaluated by simulation and its result shows that the proposed protocol outperforms the original DQRUMA/MC-CDMA protocol in terms of average total delay for data traffic and packet loss rate for voice/video traffic
