Beidou anti-broadband interference module, antenna and terminal

Abstract

The invention discloses a Beidou anti-broadband interference module, an antenna and a terminal, and belongs to the technical field of wireless. The Beidou anti-broadband interference module comprises a radio frequency sub-module and a baseband sub-module which are integrated together, wherein the radio frequency sub-module comprises m N-channel radio frequency chips, and each N-channel radio frequency chip is used for receiving N identical first analog signals at the same time and outputting N second analog signals; the baseband sub-module comprises m N-channel analog-to-digital conversion chips and an FPGA chip, and the N-channel analog-to-digital conversion chips are used for receiving N second analog signals output by the corresponding N-channel radio frequency chips and converting the received N second analog signals into serial digital signals; the FPGA chip is used for carrying out anti-broadband interference processing on the serial digital signals output by the N-channel analog-to-digital conversion chips. According to the technical scheme provided by the embodiment of the invention, the broadband interference on the signals of a Beidou satellite navigation system can be resisted.

Description

technical field [0001] The present application relates to the technical field of wireless communication, in particular to a Beidou anti-broadband interference module, antenna and terminal. Background technique [0002] As the Beidou satellite navigation system is becoming more and more perfect, Beidou satellite navigation products have achieved large-scale popularization and promotion in the civilian and military fields, getting rid of the constraints of foreign navigation systems. [0003] However, in practical applications, since the signal frequency characteristics and modulation characteristics of the Beidou satellite navigation system are well known, and the signal carrier-to-noise ratio of the Beidou satellite navigation system is relatively low, the signal of the Beidou satellite navigation system is susceptible to broadband interference. Broadband interference refers to malicious users deliberately transmitting signals with a frequency domain width covering the entir...

[0003] However, in practical applications, since the signal frequency characteristics and modulation characteristics of the Beidou satellite navigation system are well known, and the signal carrier-to-noise ratio of the Beidou satellite navigation system is relatively low, the signal of the Beidou satellite navigation system is susceptible to broadband interference. Broadband interference refers to malicious users intentionally transmitting signals with a frequency domain width covering the entire frequency band on the frequency band of the Beidou satellite navigation system, so that the signal of the Beidou satellite navigation system is interfered

[0004] Beidou satellite navigation system is likely to fail due to broadband interference
