Spectral efficiency of CDMA uplink cellular networks

In this contribution, the performance of an uplink CDMA system with random spreading and multi-cell interference is analyzed. A useful framework is provided in order to determine the base station coverage for wireless flat fading channels with very dense networks (in the number of users per meter) considering different receiver structures at the base station, namely the matched filter, the Wiener filter and the optimum filter. Using asymptotic arguments, analytical expressions of the spectral efficiency are obtained and provide a simple expression of the network capacity based only on a few meaningful parameters.
