Abstract In this paper a novel joint CDMA/RTDMA MAC for multimedia transmission in wireless network is studied. In this scheme, the resource unit allocated by the base station is changed from a slot to a code-slot. Thus it enhances the system’s capacity and can support multi-media service more efficiently. The voice packet dropping probability and data delay are analyzed through M/M /n/m model and phase process respectively. Compared to the original RTDMA, this new MAC protocol can provide multiple services’ QoS even under the heavy load.
