| Research Abstract |
It is important to realize mobile broadcast systems that transmit efficiently data from one base station toward multiple mobile terminals, called users. Multiple-input multiple-output (MIMO) transmission has been used to improve spectral efficiency for single-user systems, and can be utilized for broadcasting.
In this research, we proposed and analyzed data-dependent user selection as a communication scheme suitable for mobile MIMO broadcasting. In order to estimate channel state information used in the proposed user selection, we also proposed and analyzed joint channel and data estimation.
