Multi-input multi-output (MIMO) transmission with multiple antennas, which performs parallel transmission at the same time and frequency and enhances the channel capacity, has attracted attention. In the case of small mobile terminals, the limitation of spaces for the multiple antennas leads to degrade the improvement of the channel capacity in proportion to the number of the antennas. This paper...
MIMO channel emulation systems have been studied and developed to achieve the evaluation for the MIMO transmission technique of user equipments (UEs) with multiple antennas. The system can generate a multipath with a spatial signature by transmitting signals from multiple probe antennas set around the UE. The resolution of the emulated spatial distribution of the multipath is improved as the number...
