The Design of Wide Interval FH Sequences Based on AES

Abstract

For utilization of frequency diversity in frequency hopping (FH) communication to enhance the anti-jamming performance of FH system and improve the transmission reliability under multipath fading channel, FH communication usually hope the launch of the two carrier frequency interval is than a specified value in the adjacent frequency hopping time slot. This paper designs a new FH sequences generator based on AES block cipher, and tests the interval characteristics of the FH sequences produced by the generator. The test results show that the interval of the FH sequences are similar to the ideal values, which can satisfy the requirements of wide interval characteristics of FH codes in the FH communication systems.
