TL;DR: In this article, the authors proposed a method and a system for muting a civil aviation receiver, which comprises the steps of acquiring energy of carrier signals in received signals, acquiring a radio-frequency channel gain coefficient and a correction coefficient of the receiver; acquiring a quality parameter of the received signals according to the energy of the carrier signals, the radio frequency channel gain coefficients and the correction coefficient; and carrying out muting treatment on the received signal when the quality parameter meets a muting condition.

TL;DR: In this article, the authors proposed a method and a system for setting a mute threshold of a civil aviation receiver, which comprises the steps of acquiring noise signals inside the receiver, and acquiring a background noise correction coefficient according to the inside noise signals; acquiring calibrating signals received by the receiver; and setting the muted threshold of the receiver according to background noise corrected coefficient and the quality information correction coefficient.
