Hybrid TDMA/CDMA multiple access protocol for multi-media communications

Abstract

A novel hybrid TDMA/CDMA multiple access protocol for multi-media communications is proposed. Its performance in terms of throughput, delay and spectrum efficiency is evaluated using computer simulation. Voice, and variable bit rate data traffic are integrated within one TDMA frame through a movable-boundary structure. Combined with DS-CDMA a new hybrid multiple access protocol is investigated that is capable of integrating different types of traffic and also gives us the capacity and flexibility of the CDMA protocol.
