Abstract : |
The goal of this paper is the adaptation of the "Simultaneous MAC Packet Transmission (SMPT) " approach to a CDMA based mobile communication system with a varying number of mobile users. SMPT attempts to stabilize the Quality Of Service (QoS) of a wireless CDMA system in terms of throughput, loss rate and delay even if the propagation conditions on the wireless medium change dramatically. In the future there will be highly heterogenous QoS requirements by the mobile users. To support these requirements the network has to maximize the spectral ecency by statistical multiplexing of the used channels. We apply this mechanism to all mobile users within one wireless cell and investigate the spectral ecency. The suitability of our approach is shown by observing its eects on typical QoS parameters of multimedia applications by simulations. I., |
