Use of Diversity to Improve FH/MFSK Performance in Worst Case Partial Band Noise and Multitone Jamming

Abstract

The performance of an uncoded frequency-hopped (FH), M-ary frequency-shift keyed (MFSK) communication system can be severely degraded by worst case partial band noise or multitone jamming. This paper demonstrates that time diversity, a simplified form of coding, will effectively recover most of this jamming loss, particularly at low error rates.
