FH/MFSK Performance in Multitone Jamming [PDF]
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)

Effective power analysis of multi-tone excitation transmitting system
Inter-modulation would occur when the transmitting system is under multi-tone excitation; therefore, the non-linear response of power amplifier unit should be considered in the system design.

Development of Multitone Jamming Technique Using DDS Core in FPGA [PDF]
Communication is very important in warfare. Dispatch riders were used in ancient warfare, but communication system is used in modern warfare, as the advancement of communication equipments. In order to weaken enemy military strength, communication jamming signal disrupts enemy communication systems.

Performance analysis of FFH/MFSK receivers with self-normalization combining in the presence of multitone jamming [PDF]
An analytical study is presented for the performance of fast frequency-hopping (FFH) self-normalized orthogonal M-ary frequency-shift-keyed (MFSK) noncoherent receivers in the presence of multitone jamming. The multiple equal-power jamming tones are assumed to correspond to some of the possible FFH/M-ary orthogonal signaling tones.

Conventionally, fast frequency hopping (FFH) is regarded as a non‐coherent system, which has inevitable shortcomings in low spectral efficiency. To achieve a high spectral efficiency while maintaining a favourable bit error ratio (BER) performance in FFH systems, in this study, the authors extend their previously proposed subset‐based coherent FFH (S ...

On Maximum-Likelihood Detection for Non-coherent FH/BFSK in Multitone Jamming
We derive the optimum maximum-likelihood (ML) non-coherent detector for FH/BFSK systems in the environment of multitone jamming and additive white Gaussian noise with no aid of jamming state indication and the resultant signal-plus- jammer tone, which, however, were required in K. C. Teh’s previous work [1].
