Abstract

A Multiple-Input Multiple-Output (MIMO) communication system is described. The system may include a transmitting device having at least two transmitting antennae, each of the at least two transmitting antenna is configured to form and/or steer directional beam signals, and a receiving device having at least two receiving antennae. The transmitting device and the receiving device are configured and disposed such that illuminated spots at the receiving device produced by the beam signals of the transmitting antennae are smaller than spatial separation between neighboring receiving antennae and/or resolution spots from the receiving antenna are smaller than spatial separation between the transmitting antennae.

Claims

11. The device of claim 1, wherein the device is further configured to communicate with a plurality of receiving devices.

7. A device comprising:

at least two transmitting antennae, each antenna being configured to form and/or steer directional beam signals,

wherein the device is configured to communicate with a receiving device having the same number of receiving antennae as the transmitting antennae on the device disposed such that resolution spots from the receiving antennae are smaller than spatial separation between neighboring transmitting antennae, wherein each of the resolution spots is associated with an area covered at a certain distance by a lobe of the receiving antennae.

8. The device of claim 7, wherein the transmitting antennae are configured to transmit mm-wave signals.

9. The device of claim 7, wherein the device is enabled to apply MIMO baseband processing to a signal being transmitted.
