Abstract

The invention provides an analog beam forming method, a receiver and a communication device, and the method comprises the steps: receiving a plurality of beams through an antenna array; under the condition that interference exists in the multiple wave beams, determining the direction where the interference is located; applying an additional weight value to the antenna array according to the direction in which the interference is located so as to switch off a signal channel of an antenna unit of at least one corner of the antenna array when the plurality of beams are gained; and combining the plurality of gained beams to obtain an analog beam. According to the scheme, the receiving gain in the direction where interference is located can be restrained, the gain loss can be reduced, meanwhile, interference signals in analog beams are reduced, cost cannot be increased, and signal delay cannot be generated.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an analog beam forming 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 vertical and horizontal beams in a two-dimensional angle, and the beams can be set to form sectors or hotspots to form spatial isolation and realize user multiplexing. [0003] In the process of forming the analog beam, the antenna gain can be performed by setting weights (usually phase offsets) for the antenna units and combining the weighted antenna units. figure 1 and figure 2 They are the structural diagrams of the analog transmitter and the analog receiver respectively, combined with figure 1 and figure 2 As shown, the signals are combined after an analog phase shift. [0004] image 3 is a schematic diagr...
