Abstract
A space-time grouped multi-user detection algorithm based on SAGE algorithm in out-of synchronous TD-SCDMA system with strong MAI is proposed. Based on the information of DOA of up-link signal,the multi-path signals are amalgamated under the max ratio principle and users are grouped in the space field ,multi-user detection is carried out in every group,then SAGE algorithm are adopted to cancellthe jamming .Simulation results show that out-of synchronous scenario with strong MAI demonstrate that the proposed algorithm exhibits better performance than conventional detector, such as marched filter,joint detection and decorrelation algorithm.关键词
