Abstract

The invention discloses an interference signal suppression device, which comprises a low noise amplifier module, a signal conversion module, a signal processing module and a power amplifier module. Inputted radio frequency signals are processed by the low noise amplifier module, the signal processing module and the signal conversion module and are then amplified and outputted by the power amplifier module. The signal conversion module is used for carrying out gain control on the signals inputted by the low noise amplifier module, carrying out first conversion processing on the signals after gain control, outputting the signals to the signal processing module, carrying out second conversion processing on the signals outputted by the signal processing module and outputting the signals to thepower amplifier module. The signal processing module is used for controlling the signal conversion module for gain control and carrying out gain compensation processing on the signals after first conversion processing. The invention also provides a method of suppressing strong interference signals. According to the device and the method disclosed in the invention, the communication quality of network communication equipment can be improved, the reliability of a communication system is improved, and the effect of expanding the application scenario of the communication system can be achieved.

Description

technical field

[0001] The invention relates to the technical field of network communication, in particular to an interference signal suppression device and a method for suppressing strong interference signals. Background technique

[0002] With the rapid development of communication technology, the spectrum resources for communication are becoming more and more tight. As the spectrum is used more and more intensively, duplexers, dielectric filters, etc. are usually used to suppress interference signals in specific frequency bands during spectrum use. Passive components are filtered. Usually, passive devices are easier to meet the design requirements for the suppression of out-of-band 5MHz, 10MHz, etc., but when the frequency band to be suppressed is very close to the useful frequency band, such as out-of-band 2.5MHz, etc., it will cause interference with the useful communication frequency band. Strong interference will cause network call drop, or even unreachable situation...
