Generation of Chaotic Frequency Hopping Codes and Its Application in Communications

Based on the logistic map and the idea of symbolic dynamics, chaotic frequency hopping (FH) codes are generated by using the return map. The codes have good performance, and are more immune to prediction and interception. Furthermore, an FH-CSK communication system is designed and realized. The theoretical analysis and simulation results show that the system has good performance over the AWGN and multipath channels
