Abstract

The embodiment of the invention discloses a method for adaptively calculating a forming factor, and relates to the technical field of wireless communication. The method comprises the steps: acquiringpilot frequency data of an antenna; acquiring an initial position of the pilot frequency data, and extracting a pilot frequency signal of the antenna; extracting a synchronous pilot frequency from the pilot frequency signal of the antenna, iteratively updating the synchronous pilot frequency and a local pilot frequency, and calculating an initial forming factor; and performing iterative updatingaccording to the initial forming factor and the local pilot frequency, and calculating a latest forming factor. With the method disclosed by the invention, a problem that the beamforming factor calculation is not accurate enough as well as a problem that the LMS convergence speed is slower than the RLS speed is solved, and the convergence can be performed quickly and the tracking can be performedstably.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular to a method and device for adaptively calculating a shaping factor. Background technique [0002] Beamforming, also known as beamforming and spatial filtering, is a signal processing technique that uses sensor arrays to send and receive signals in a directional manner. The beamforming technology adjusts the parameters of the basic unit of the phase array, so that signals at certain angles obtain constructive interference, while signals at other angles obtain destructive interference. Beamforming can be used at both the signal transmitting end and the signal receiving end. However, in the prior art, there is generally a problem that the calculation of the beamforming factor is not accurate enough. Contents of the invention [0003] In view of the above-mentioned technical problems in the prior art, embodiments of the present disclosure propose a method...
