A Slow Frequency Hopping Technique that is Robust to Repeat Jamming

Julian Blanchard

Open publisher page 9 citations

Abstract

A frequency hopping technique capable of defeating the repeat jammer independent of the hop rate is presented. This technique, random frequency shift keying/frequency hopping (FSK/FH), is described and analyzed. Specific results are given for 2-ary, 4-ary and 8-ary random FSK/FH against repeat noise, repeat tone, and combined repeat tone and noise jamming with and without error correction coding. These analyses show that random FSK/FH is an effective countermeasure to the repeat jammer.
