Embodiment
Below in conjunction with accompanying drawing the utility model is done further description:
As shown in Figure 1; Smart antenna multi-user interference checkout gear; It is an independent equipment or integrated with other equipment; It comprises a plurality of smart antenna receiving elements, filter unit, RF processing unit, signal demodulation unit, base station information processing unit, isolation acquiring unit, disturbs judging unit, display unit and interference processing unit; Wherein, the output of each smart antenna receiving element links to each other with the input of filter unit, and the output of filter unit links to each other with the input of RF processing unit; The output of RF processing unit links to each other with the input of signal demodulation unit; The output of signal demodulation unit links to each other with the input of isolation acquiring unit and the input of base station information processing unit, and the output of base station information processing unit links to each other with the input of isolation acquiring unit, and the output of isolation acquiring unit links to each other with disturbing judging unit; Disturb the output of judging unit to link to each other with disturbing processing unit, display unit is with signal demodulation unit, base station information processing unit, interference judging unit and disturb processing unit to link to each other.
The course of work of the utility model: a plurality of smart antenna receiving elements receive signal, the signal that receives are sent to filter unit, through filtering unit filters; And filtered signal sent to RF processing unit, RF processing unit is handled the signal that receives, and the signal after will handling sends to signal demodulation unit; Signal demodulation unit carries out demodulation to the received signal, judges whether to exist interference signal, if exist; Then with pilot signal amplitude that demodulation obtained and send to the isolation acquiring unit, the base station pilot information that demodulation obtained is sent to the base station information processing unit, if do not exist; Then directly show noiseless at display unit; The base station information processing unit obtains the corresponding signal power of each signal source sign and each signal source sign and sends to the isolation acquiring unit, the pilot signal amplitude that the isolation acquiring unit sends according to signal demodulation unit according to the base station pilot information that signal demodulation unit sends; And each signal source sign and each signal source that the base station information processing unit sends identify corresponding signal power; Obtain isolation and send to the interference judging unit, the isolation and the predefined isolation thresholding that disturb judging unit to send according to the isolation acquiring unit are judged annoyance level; If the isolation of receiving is less than predefined isolation thresholding; Then correspondingly disturb processing, the result of base station information processing unit, interference judging unit, interference processing unit all can show at display unit, facilitates consultation.
