Problems solved by technology

Theoretically speaking, the optimal beamforming effect can be achieved by using digital beamforming. For details, see figure 2 , phase information can be added to the data to be sent 1, 2...n, but due to the addition of multiple digital-to-analog conversion devices, its cost and power consumption are much higher than analog beamforming

Embodiment Construction

[0044] In order to realize flexible control of beamforming, in the embodiment of the present invention, no analog phase shifter is used for phase adjustment, and further phase shift control of each radio frequency signal is added in the extended phase shift control network. And adopt the method of expanding the phase to improve the precision of the phase control.

[0045] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0046] refer to image 3 As shown, in the embodiment of the present invention, the control system for realizing numerically controlled analog beamforming specifically includes:

[0047]At least two phase shifters 1 are used to adjust the phases of the respectively obtained data to be transmitted according to respective preset angles;

[0048] Of course, if image 3 As shown, the data to be sent needs to be processed by digital-to-analog conversion and frequency up-conversion bef...

Abstract

The present invention relates to communication technology, in particular to a control method, device and system for beamforming. Flexible control for beamforming. The system is: by adding an extended phase-shift control device between each group of power amplifiers and antenna elements, further phase-shift control of each radio frequency signal (that is, the data to be sent) is added, that is, the method of extending the phase is used to improve Accuracy of phase control. In this way, an extended phase-shifting control architecture is constructed to make up for the low phase accuracy of analog beamforming. Combined with the antenna array element, it can further make fine-grained This allows for more precise phase control, enabling the control of radio frequency signals with a higher degree of precision, as well as beamforming control.

Description

technical field [0001] The present invention relates to communication technology, in particular to a control method, device and system for beamforming. Background technique [0002] With the rapid development of communication technology, the application of wireless mobile broadband will become more and more extensive. Portable mobile devices will use very high frequency bands for data communication, such as centimeter wave, millimeter wave and so on. Due to the carrier frequency and the influence of the environment, the loss of signal propagation is very high. In order to solve this problem, the general approach is to use beamforming technology in portable mobile devices for path loss compensation to ensure link quality; for example, using Multiple antennas form an array and use beamforming to increase gain to ensure link quality. [0003] Under the existing technology, digitally controlled phase shifters are usually used for high frequency band signals, refer to figure 1 ...
