Abstract
A beamforming system synchronization architecture is proposed to allow a receiving device to synchronize to a transmitting device in time, frequency, and spatial domain in the most challenging situation with very high pathloss. A detector at the receiving device detects the presence of control beams, synchronizes to the transmission and estimates the channel response by receiving pilot signals. The detector has low complexity when exploiting the structure of the pilot signals. The detector consists of three stages that break down the synchronization procedure into less complicated steps. The detector accurately estimates the parameters required for identifying the transmit device and performing subsequent data communication.
