Abstract

A backhaul radio is disclosed that operates in multipath propagation environments such as obstructed LOS conditions with uncoordinated interference sources in the same operating band. Such a backhaul radio may use adaptive beamforming and sample alignment at the transmitter to enhance the link performance. Such backhaul radios may communicate with each other to compute and apply optimal beamforming parameters for a particular propagation environment through a closed-loop feedback mechanism.
