♦ The present RUSK hardware is ready for MIMO measurements
· Up to 1024 channels, e.g., 16 transmit and 64 receive antennas
♦ Improvements are desirable especially for directional parameter estimation
· Example:
- Resolution of azimuth and elevation requires planar arrays at both sides,
8x8 uniform rectangular arrays yield 4096 channels
· The ratio of the measurement repetition time and the total snapshot duration
gets smaller with a larger number of channels [see the time diagram].
The arising need for continuous recording of the receive signals requires
a sophisticated storage concept
♦ The new generation RUSK system is prototyped within the HyEff project

- 16384 channels, freely configurable for RX- and TX- multiplexing
