A Kind of Chaotic Synchronous Catch Scheme Based on DSP

The Chaotic frequency hopping sequence can improve the reliability, secrecy and anti-jamming performance in the underwater acoustic communication, but it′s hard to realize the synchronization. According to the underwater acoustic channel characteristics of chaotic sequence based on Logistic map, a synchronous scheme based on DSP hardware platform in diminutive underwater automatic testing system is proposed. Both the coarse and subtle synchronization are realized, and the feasibility is verified by the outfield experience results.
