Research Of RS Coding Interweaving Modulation And Frequency Hopping Pattern In Frequency Hopping Communications

Channel coding, modulation and Frequency hopping pattern are of great importance in Frequency hopping communication module. Rationally designing and implementing these modules is important to realize efficient and safe data communication in Frequency hopping.In this paper, based on MATLAB platform, it simulates and carries out research on the three parts of Frequency Hopping, including channel coding, digital modulation and Frequency hopping pattern. In the channel coding module, Reed-Solomon coding (RS) is adopted. It implements and optimizes the RS algorithm from the time domain, and mainly researches on RS decoding process as well as interweaving method. In the modulation module, MSK modulation is adopted. The modulation and demodulation of MSK is introduced and simulated in this paper. At last, in the Frequency hopping pattern module, time hopping and frequency hopping are both used. One is symmetrical time pieces and unsymmetrical time sheets frequency hopping pattern, and the other is unsymmetrical time pieces frequency hopping pattern.At the end of this paper, each module is simulated and analyzed, and the results are cocluded.
