Abstract

The invention discloses an intelligent spectrum agility semi-physical simulation experiment system and method based on USRP. The semi-physical simulation experiment system comprises a frequency tube center, a wireless service sending end, a wireless service receiving end and a jammer. The frequency tube center is composed of a computer, a USRP 2920 and an antenna; each wireless service transceiving module is composed of a computer, a USRP 2943, a USRP 2920 and an antenna; wireless networks with two frequency bands are configured in an experimental environment, the first network is a service wireless network with the frequency band ranging from 2 GHz to 2.2 GHz, and the second network is a frequency tube wireless network with the frequency band ranging from 1.65 GHz to 1.85 GHz. According to the invention, intelligent frequency spectrum management can be realized, the frequency spectrum utilization rate is effectively improved, the communication quality is improved, the frequency spectrum agility algorithm can be verified, the time and the cost required by development are reduced, and the method has a good promotion effect on realizing intelligent frequency spectrum agility and improving the robustness of the communication quality.

Description

technical field [0001] The invention belongs to the field of electromagnetic spectrum anti-interference, in particular to a USRP-based intelligent spectrum agility semi-physical simulation experiment system and an experiment method. Background technique [0002] Electromagnetic spectrum resources are intangible resources that belong to the state. Its application is spread across various industries, and it plays a very important role in military, civilian and other fields. At the same time, spectrum is a limited, non-renewable strategic resource, most of which are used for civilian use, and only a part is used for the military. In the future, there will be a large number of battlefield equipment, a complete range of types, a high density of radio stations, and a fast-paced change in the electromagnetic environment. Therefore, limited Scientifically and rationally divide and manage spectrum resources, reduce communication interference, ensure more spectrum advantages in inform...
