The modeling of wideband DS-CDMA uplink channel for the third-generation mobile communications

In this paper, firstly the uplink channel structure is described, based on wideband DS-CDMA in detail, then a mathematics uplink channel model of wideband DS-CDMA is proposed, including system model, channel model, and received signal model. About the tool selection, Matlab6.1 is suggested and shown the convenience. Finally, the mathematics model and the revised Matlab6.1 model are both verified feasible by BER, and are analyzed respective in which kind of channel estimation way they can be used.
