This article briefly discusses the frequency hopping communication system in the frequency hopping pattern requirements and indicators. The performance and existing problems of using m sequence in frequency hopping pattern are analyzed preliminarily. The application of Reed-Solomon code in frequency hopping communication system is emphatically introduced. The correlation and autocorrelation properties of (n, b) R-S codes are analyzed. It is proposed to generate a frequency hopping pattern using a subset E’_1 of (q-1,2) R-S codes, and the performance of such a code is analyzed. Finally, the confidentiality of the R-S code hopping pattern is also discussed.
