FH/MFSK performance in multitone jamming [PDF]

open access: greenIEEE Journal on Selected Areas in Communications, 1985
The performance of frequency-hopped (FH) M -ary frequency-shift keyed (MFSK) signals in partial-band noise has been extensively analyzed in the open literature. This paper extends the previous research to the usually more effective class of multitone jamming. Specifically, this paper will 1) categorize several different multitone jamming strategies; 2)

Performance Analysis of the Optimal Multitone Jamming for a MFSK-FH System [PDF]

open access: hybrid
The analysis and evaluation of jamming becomes very important with the strain of spectrum resources and the intensification of electronic countermeasures. In order to deepen the understanding of the mechanism of multitone jamming (MTJ) on multiple frequency shift keying and frequency-hopping (MFSK-FH) system, as well as support the communication ...

Performance analyses of fast frequency-hopped communication systems against multitone jamming and multiple-access interference [PDF]

open access: gold, 2007
181 p. Spread-spectrum (SS) is a modulation technique that can be used to mitigate the deleterious effects of intentional or unintentional interference and multi-path reception. Fast frequency-hopped (FFH) SS communication system is one of the very important techniques commonly used for SS communication systems.

Multitone jamming rejection of FFH/BFSK linear-combiningreceiver over Rayleigh-fadingchannels

open access: closedElectronics Letters, 1998
A computationally efficient BER expression for an FFH/BFSK linear-combining receiver against multitone jamming and AWGN over Rayleigh-fading channels is derived based on a Taylor series expansion. The analytical expression, validated by simulation results, allows us to efficiently analyse the system performance with higher diversity levels, which is ...
