| Summary: | A new OFDM data link model based on OCML is proposed to solve the problem of reliability of data link of air-to-ground radar. The above model uses OCML spatiotemporal chaotic sequence to improve CCSK soft spread spectrum, and simulates with coding and modulation techniques. Simulation analysis shows that the new OFDM data link model based on OCML can effectively improve the reliability of pseudorandom sequences in CCSK due to poor autocorrelation, significantly improve the bit error rate of the system and effectively improve the reliability of air-to-ground radar data chain. |
