Abstract

In this paper the performance of a dual antenna reception in WCDMA downlink is studied on the link and network levels for circuit switched service of 64 kbps. An effect of penetration diversity terminals and channel parameters to potential diversity gain are investigated from a point of view of two receivers; dual antenna RAKE and a space-time chip equalizer. Results indicate that the penetration of diversity terminals should be large before the performance gain in link level can be turned into significant increase in system capacity.
