Abstract

The invention discloses an adaptive beam scanning tracking method and device for a millimeter wave band. The method comprises the following steps: determining whether to enter a beam scanning trackingmode according to a system CRC check code; switching between an only transmitter scanning mode or a transmitter-receiver scanning mode according to user selection; if it is the only transmitter scanning mode, controlling a transmitter array antenna radio frequency device to perform global search type scanning by taking the codebook number as the cycle index; updating the energy of the received signal in the scanning process and recording an optimal codebook; if it is the transmitter-receiver scanning mode, embedding a round of receiver scanning cycle in each cycle in the process. By means ofthe high-frequency and broadband characteristics of millimeter waves, the high throughput rate is achieved, and the stability of system transmission can be guaranteed.

Description

technical field [0001] The invention relates to an adaptive beam scanning and tracking method and device in the millimeter wave frequency band, and belongs to the technical field of wireless communication systems. Background technique [0002] Beamforming technology is one of the results of the combination of digital signal processing technology and antenna technology. On the basis of multi-antenna (MIMO) systems, beamforming technology has been developed and matured. From the perspective of the transmitting end, custom adjustments are made to the phase or amplitude of the multi-antenna array, so that the electromagnetic waves are superimposed in the beam domain, and the beam can be changed from the original omnidirectional to directional. The directional beam has a higher degree of discrimination between the main lobe and side lobes, which is more conducive to transmission. From the perspective of the receiving end, performing different weights (phase or amplitude) on the...
