Anti-interference spectrum situation intelligent sensing system

Abstract

The invention discloses an anti-interference spectrum situation intelligent sensing system, relating to the technical field of communication anti-interference. The anti-interference spectrum situationintelligent sensing system comprises the following parts: a display module, a channel connection module, a processing module and hardware equipment, wherein the display module is used for displayingvarious feedback data, and can directly feed back and acquire real-time frequency spectrum situations; the channel connection module is used for receiving and sending data transmission; the processingmodule is used for processing and arranging signals received and sent by the channel connection module; and the hardware equipment is used for processing data output by the processing module and facilitating application of different equipment. According to the anti-interference spectrum situation intelligent sensing system, broadband and wireless transmission are fused; external malicious interference is effectively avoided; a method of generating a spectrum frequency band perception frequency point sequence is adopted, spectrum data is sorted and circularly configured with receiving parameters of USRP equipment, the overall throughput and the anti-interference performance of a network are improved, the flexibility is good, the hardware reconfigurability and the expandability are high, intelligent anti-interference can be achieved through the combined anti-interference module, and the communication quality of a user is guaranteed.

Description

technical field [0001] The invention relates to the technical field of communication anti-jamming, in particular to an anti-jamming spectrum situation intelligent sensing system. Background technique [0002] With the rapid development of wireless communications, spectrum resources are becoming increasingly scarce. A large number of research reports of the US Federal Communications Commission (FCC) show that the utilization rate of the current wireless spectrum is very low, only 15% to 85%. Among them, the uneven allocation of spectrum resources is a very important factor. The existing static spectrum resource allocation method leads to the waste of spectrum resources when some licensed frequency band users are idle, while the unlicensed frequency band is extremely crowded. Cognitive radio technology can perceive and utilize the idle spectrum in the surrounding environment, so that unlicensed users can access the spectrum. Multiple antennas are installed at the transmitti...
