Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] Such as figure 2 As shown, the antenna system realized by the present invention includes a phased array antenna, a turntable, a turntable controller and a control device. The phased array antenna is arranged on the turntable, the turntable is controlled by the turntable controller, and the control device realizes Control of the turntable controller.

[0045] The wireless communication system loads available information onto radio waves or radio frequency waves, and then uses antennas to transmit and receive radio waves, thereby realizing communication between devices. The antenna also has...

Abstract

The invention discloses a control method based on antenna control system. The method utilizes a station rotation controller, a control device and the communications between antennas to complete the control over the antennas including the startup, the system initialization, the connection establishment, the input of wave number or attenuation required to be selected. In the method, the wave number or attenuation is packaged according to a communication format, and the packaged data are then transmitted to the station rotation controller. With the invention, it is possible to realize the adjustment of the beam angles, the directions and the powers of the antennas; the accuracy of the antenna angle control is increased; the radiation angles of the antennas are also increased and the performance of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a method for controlling an omnidirectional communication antenna of a cognitive radio system. Background technique [0002] Cognitive Radio (CR) is a controllable spectrum sharing technology. It can continuously perceive changes in the wireless environment, and use controllable technology to adjust system parameters (such as transmit power, carrier frequency, etc.) Spectrum reuse can achieve high spectrum utilization. In particular, unlicensed users, that is, secondary users (seconddary users, SUs) can be allowed to use spectrums of licensed users, that is, primary users (primary users, PUs). In the face of non-renewable radio spectrum resources, when sharing the spectrum with licensed users, the SU will definitely cause some interference to the PU, so how to suppress these interferences and meet the communication quality requirements of the SU without affecting t...
