Embodiment Construction

[0063] In order to make the purpose, technical solution and advantages of the present application clearer, the present application 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 application, and are not intended to limit the present application.

[0064] The working channel calibration method of the smart antenna provided by this application can be applied to such as figure 1 shown in the application environment. Among them, the calibration unit 11, the calibration channel 12 and the working channel 13 are connected to each other by communication; taking the calibration reception as an example, the calibration unit 11 sends the training sequence to the calibration channel 12 in the form of a calibration signal, and the signal passes through the calibration channel 12. Each working channel 13 receives, and the calib...

Abstract

The invention relates to a working channel calibration method and device of an intelligent antenna, intelligent antenna equipment, a storage medium, an application-specific integrated circuit and a programmable logic circuit, and the method comprises the steps: obtaining a sampling point sequence of a working channel passing through the intelligent antenna for multiple times, and determining a plurality of first measurement parameter sets of the working channel according to the sampling point sequence; combining the plurality of first measurement parameter sets of the working channel to obtain a measurement parameter combination; extracting the measurement parameters with the maximum quantity from the measurement parameters of each category as a second measurement parameter set; determining an average value of various types of measurement parameters from the plurality of second measurement parameter sets as a channel measurement parameter of the working channel of the intelligent antenna; and calibrating the working channel by using the channel measurement parameter to obtain a calibrated working channel. According to the method, iterative measurement and calibration are carried out on a working channel, a calibration result is judged, and alarm information can be generated if necessary; and the calibration efficiency of the working channel of the intelligent antenna is improved.

Description

technical field [0001] The present application relates to the technical field of wireless communication, in particular to a working channel calibration method and device of a smart antenna, smart antenna equipment, storage media, application specific integrated circuits and programmable logic circuits. Background technique [0002] The calibration of the working channel is one of the core key technologies of the smart antenna. In the smart antenna system, due to reasons such as processing, device aging, and temperature changes, the antenna, the feeder, and the RF channel (collectively referred to as the channel) composed of analog devices often need to be calibrated to meet the requirements. Require. At present, the cyclic successive approximation measurement method is mainly used to obtain the measurement data before calibration. By sending the cyclic training sequence, the receiver uses the time domain successive approximation filter, and the amplitude and phase response o...
