Abstract This paper researches low complexity detection scheme based on joint transmission scheme in multi-user MIMO downlink. Firstly, a model of multi-user MIMO downlink is introduced. A data transmission algorithm is got which can greatly reduce receiver’s calculative cost for multi-user MIMO downlink. And each mobile station receiver needs only one linear filter. Then through simulation and analysis in the TD-SCDMA system, Multi-user JT MIMO demonstrates its superiority and application prosperity.
