摘要

In this paper, we design a communication system in order to improve the utilization of spectral debris using the idea of cognitive radio by detecting the spectrum of external environment to provide a reference for the avoidance of communication interference. Accordingly, a communication system transmission using the method of spectrum energy sensing, based on the software-defined radio (SDR) platform of NI company's universal software radio peripheral (USRPs) and the graphical programming language LabVIEW software, achieves a reliable dynamic access for video transmission. We also design adaptive access and frequency hopping access for the data channel and control channel, thus completing the anti-jamming communication system.
