Abstract
The present disclosure relates to data transmission between a node and peer nodes. Interference alignment techniques are used to mitigate interference between the nodes on a line of sight channel A data stream is exchanged in two transmissions between the node and a peer node. The two transmissions are formed according to an interference alignment precoding matrix. The node may include linearly aligned antennas. To mitigate further the interference between the node and the peer node, a pair of these antennas is selected for communication with the peer node as a function of a distance between the node and the peer node and as a function of a wavelength of the communication. Channel state information may be exchanged between the node and the peer node for precoding matrix selection and for antenna selection. The antennas used for communication between the nodes and the peer nodes may be beamforming antennas.
