Multi-cell Joint Detection and Macrodiversity for TD-SCDMA Trunking System
摘要
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, the macro-diversity model can be used to improve the system performance, when users of target group are distributed in different cells. The results of simulation show that joint detection and macro-diversity can significantly improve system performance.关键词
