Embodiment Construction

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] refer to figure 1 , the present invention includes a sending coupler, a variable attenuator, an intelligent interference reconstruction unit, a combiner and a receiving coupler, wherein:

[0045] Sending coupler, used to couple the small signal of the sending channel from the high-power signal of the sending channel and output it to the variable attenuator;

[0046] The variable attenuator is used to adjust the size of the small signal of the transmission channel, and output the adjusted signal A to the intelligent interference reconstruction unit;

[0047] The intelligent interference reconstruction unit is used to intelligently analyze the self-interference signal components in signal B, and reconstruct the self-interference signal through the processing of signal A, and at the same time form a memory for the reconstruction ...

Abstract

The invention discloses a meteor trail communication self-interference suppression device and method, belonging to the technical field of communication. The self-interference suppression device of the present invention includes a sending coupler, a variable attenuator, an intelligent interference reconstruction unit, a combiner and a receiving coupler. 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 can be directly applied to the meteor trail communication system, installed between the transceiver channel and the ring assembly, to suppress the self-interference signal, which can greatly reduce the self-interference signal in the receiving channel and reduce the receiving filter The indicator pressure of the device can solve the problem of system volume bottleneck.

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...
