| Outline of Final Research Achievements |
Multi-user multiple input multiple output (MU-MIMO) transmission is one of key technologies for enhancing transmission rate. However, there is an issue that power consumption becomes very large at terminal stations because signal processing in MU-MIMO is basically required for both base and terminal stations. In this research, hardware configuration of very large MIMO, where the base station has a large number of antennas and the signal processing at the base station is simplified and that at the terminal stations is eliminated, is proposed and evaluated by computer simulation and measurement. It is shown that the effectiveness of proposed configuration is verified from points of views on antennas, propagation measurement, testbed of transceivers, and system evaluation.
