Joint Transmission,Combined Multi-user MIMO System in TD-SCDMA Dowlink
Uo X · 2006
This paper researches joint transmission scheme combined multi- user MIMO system, in which the receiver algorithms are a priori chosen, whereas the algorithms to be used at transmitter have to be a posteriori adapted under consideration of channel state information and the receiver algorithms. Firstly, a model of multi- user MIMO downlink is introduced. We get a data transmission al- gorithm which can greatly reduce receiver' s calculative cost for multi- user MIMO downlink. Then through simulation and analysis in the TD- SCDMA system, Multi- user JT MIMO demonstrates its superiority and application prosperity.
