Embodiment Construction
[0351] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0352] The background technology of the embodiments of the present invention is introduced below.
[0353] A wireless transmitter (such as a base station, terminal) with multiple antennas can transmit wireless signals by forming beams pointing in specific directions through beamforming. The width and direction of the beam can be flexibly adjusted by applying appropriate weights on each antenna element. Beamforming can be performed in the digital or analog domain. When each antenna unit has an independent baseband module, each antenna unit can independently control the amplitude and phase of the signal transmitted on the antenna unit, so that digital beamforming can be realized. ...
