Abstract

Broadcast transmission is used in the downlink for TD-SCDMA trunking systems in the same frequency and same time slot, so the MAI of multi-cell is very serious. In this paper, we discuss the classical joint detection algorithms used for interference suppression. Considering the characteristics of trunking system, we can consider multi-cell model as macro-diversity model, when users of target group are distributed in different cells. We simulate under three different channel models (described in section 2), and it is shown that joint detection and macro-diversity can significantly improve system performance. The impairing effect of error propagation on macro-diversity depends on the distribution of the target group.

Keywords: TD-SCDMA trunking system multi-cell channel estimation multicell joint detection macro-diversity
