Uplink performance of a new macro-diversity cellular mobile radio architecture

This article analyses the uplink performance of a new mobile radio network architecture with overlapping cells and macroscopic diversity with regard to outage probabilities. Results are obtained by computationally efficient analytical/numerical evaluation of cumulative density functions. Various combining schemes are investigated, taking into account correlated lognormally distributed carrier and interferer signals. Comparisons of the new with conventional cellular architectures show significant improvements with respect to shadow fading. The gains obtainable by the new macroscopic diversity architecture may not only be used to increase the transmission quality or decrease the outage probabilities, but also to considerably lower the channel re-use factor, thereby solving capacity problems for so-called “hot spots”
