Abstract

The invention discloses a meteoric trail communication self-interference suppression device and method, and belongs to the technical field of communication. The self-interference suppression device comprises a transmitting coupler, a variable attenuator, an intelligent interference reconstruction unit, a combiner and a receiving coupler. In order to improve the communication efficiency, the meteoric trail communication system mostly adopts a frequency division duplex mode; however, the meteoric trail communication system can be directly applied to the meteoric trail communication system because the meteoric trail communication system works in a VHF (very high frequency) frequency band, the transmitting power generally reaches a kilowatt level, only a band-pass filter with a large size can be adopted to ensure the system performance, and the maneuvering characteristics and the cost of the system are not facilitated. The device can be directly applied to a meteoric trail communication system; wherein the device is installed between a receiving and transmitting channel and an annular assembly to carry out self-interference signal suppression, so that self-interference signals in a receiving channel can be greatly reduced, the index pressure of a receiving filter is reduced, and the problem of volume bottleneck of a system is solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a meteor trail communication self-interference suppression device and method, which can be applied to a meteor trail communication system. Background technique [0002] Meteor trail communication is a burst communication, which has good anti-jamming, anti-interception and anti-destruction capabilities. So far, meteor trail communication has been widely used in foreign civil and military applications. [0003] In order to improve the communication efficiency, the meteor trail communication system mostly adopts the method of frequency division duplexing. Since it works in the VHF frequency band, and the transmission power usually reaches the kilowatt level, in order to ensure the system performance, only a bulky bandpass filter can be used. Conducive to the mobility and cost of the system, the present invention relates to a meteor trail communication self-interferenc...
