Use of MIMO techniques for UWB

• Distributed MIMO usage of available nodes for coordinated transmission to extend the range of UWB devices.

Multiple UWB nodes could carry out synchronized transmissions to a user who is outside the range of a single UWB node within the system. This could be an alternative to a multi-hop network

• UWB with Multiple Antennas (c.f. Distributed MIMO)

The channel impulse responses of the UWB channel have been found to have very low cross correlation. This fact can be used to design UWB transmitters /receivers with multiple antennas in order to enhance system throughput. This might also prove advantageous in position-tracking.
