Novel Space Time Group Joint Detection for TD-SCDMA Systems
Zhang Huiqin · Dianzi Ke-ji Daxue xuebao · 2007
The joint detection is a key technique for receiver of TD-SCDMA systems,but its implementation complexity increases exponentially with the number of users.In this paper,a novel group joint detection(JD) technique based on adaptive antenna array is proposed by hybrid space time signal structure.The system performance with group JD is confirmed by computer simulation.Results show that the novel detection method can reduce the complexity of implementation with a little performance degradation.
