Abstract

This paper presents a comparative analysis of system-level TD-CDMA simulation results obtained for different shadowing simulation models. Namely, relevance of aspects such as cross-correlation or spatial autocorrelation of shadowing is studied. It is shown that, in terms of system capacity, modelling of cross-correlation plays a more important role than spatial autocorrelation. Another relevant issue that arises from the analysis is the relevance of cross-link correlation in shadowing for a time-duplexing scheme such as TD-CDMA.
