Capacity Enhancement of CDMA system through Internet Traffic Model

In the multiuser systems، after signal is received in the antenna، users will be detected by complicated processing of signals. Thus، not to waste the processing power we prefer the signal convey information on its whole time. Meanwhile we know the transmitted signals don’t contain information all the time. The Internet traffic is a non-real time traffic and owns a statistical behavior. We have utilized the packet payload information in this paper and tried to enhance the capacity through a new view on the traffic model by a new Traffic Activity Factor (TAF). In line with that in this paper we used two we proved a theorem indicating TAF effect on the capacity and also we used a signal to noise relation with TAF parameter. We used the popular traffic services such as www، ftp، email، telnet in the multiuser systems. Both methods proved our vision.
