Abstract
Research on Intelligent anti-jamming communication with Cognitive Radio
Highlights
Electromagnetic interferenceIn complex electromagnetic environment, cognitive radio technology is an effective means to resist interference
The basic principle of Non-Contiguous OFDM (NC-OFDM) is shown in Fig. 2, which is include spectrum sensing, coding and decoding, modulation and demodulation, OFDM modulation and demodulation, SNR estimation, channel estimation and other modules
Compared with the traditional OFDM technology, the basic structure of NC-OFDM is that there is more dynamic spectrum sensing at the transceiver end to eliminate the unavailable subcarriers
Summary
Cognitive radio technology is an effective means to resist interference. Both Non-Contiguous OFDM (NC-OFDM) and Transform Domain Communication System (TDCS) are waveforms suitable for discrete spectrum situations of cognitive radio scenarios, they can obtain real-time spectrum and interference distribution through spectrum sensing. Because the interference signal is often time-varying, the available spectrum is often discrete and irregular. This requires the study of smart anti-jamming technology. According to the electromagnetic interference environment, it intelligently generates the best anti-jamming method, improves the system's anti-jamming capability and spectrum utilization, and achieves efficient and EAI Endorsed Transactions on reliable anti-jamming communication. This paper explores the use of artificial intelligence algorithms such as neural networks to select the best waveform
