Problems solved by technology

[0005] However, the obvious disadvantage of the automatic gain control function is that while adjusting the receiver gain, it will reduce the ability of the receiver to receive useful signals. In other words, automatic gain control will cause the noise figure of the receiver to increase

Abstract

The present invention provides an analog beamforming method, receiver, and communication device, wherein the method includes: using an antenna array to receive multiple beams; if there is interference in the multiple beams, determine where the interference is located direction; apply additional weights to the antenna array according to the direction in which the interference is located, so as to turn off the signal path of the antenna elements of at least one corner of the antenna array when gaining the plurality of beams; After the multiple beams are combined, an analog beam is obtained. The above solution can suppress the receiving gain in the direction of the interference, and can reduce the interference signal in the analog beam while reducing the gain loss, without increasing the cost and without generating signal delay.

Description

technical field [0001] The present invention relates to the field of wireless communication technologies, and in particular, to an analog beamforming method, a receiver and a communication device. Background technique [0002] Analog beamforming typically relies on selecting a series of preset beams for transmitting and receiving data streams. The antenna array forms beams in vertical and horizontal planes in two dimensions, and the beams can be set to form sectors or hotspots to form spatial isolation for user multiplexing. [0003] In the analog beam forming process, antenna gain can be achieved by setting weights (usually phase offsets) to the antenna elements, and combining the weighted antenna elements. figure 1 and figure 2 The schematic diagrams of the analog transmitter and the analog receiver are respectively, combined with figure 1 and figure 2 As shown, the signals are combined after analog phase shifting. [0004] image 3 is a schematic diagram of an int...
