Performance analysis of FFH/MFSK receivers with self-normalization combining in the presence of multitone jamming [PDF]
IEEE Transactions on Vehicular Technology, 2002 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.

Development of Multitone Jamming Technique Using DDS Core in FPGA [PDF]
The Journal of Korean Institute of Electromagnetic Engineering and Science, 2011 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.

Multitone jamming of FH/BFSK in Rician channels
IEEE Transactions on Communications, 1999A new bit error rate (BER) expression for a noncoherent frequency-hopped binary-frequency-shift-keying (FH/BFSK) receiver in Rician channels, subjected to independent multitone and wideband noise interference, is derived. Unlike previously published analyzes, we combine the signal and jammer multipath components, the additive white Gaussian noise (AWGN)

Performance of multitone FFH/MFSK systems in the presence of jamming
IEEE Transactions on Information Theory, 1989A novel type of diversity signaling for an M-ary frequency-shift keyed modulation format involving the transmission of multiple tones on each diversity branch is considered. The properties of such a system are investigated, and its performance in the presence of tone jamming is analyzed.

Error performance analysis of FFH-MFSK with multitone jamming
Proceedings of 8th International Symposium on Personal, Indoor and Mobile Radio Communications - PIMRC '97, 2002An approach to computing the symbol error probability of fast frequency hopped M-ary frequency shift keying (FFH-MFSK) systems with majority vote is introduced. The error performances of an FFH-MFSK system threatened by a multitone jammer are analyzed.

A new anti-jam receiver for MFSK/FFH system with multitone jamming
2008 11th IEEE Singapore International Conference on Communication Systems, 2008In this paper, a differential jamming rejection (DJR) receiver in fast frequency hopping (FFH) M-ary frequency shift keying (MFSK) systems with a worst-case band multitone jamming (MTJ) is introduced. This receiver, based on detecting frequency spectrum difference in forward-backward time slot while the FFH/MFSK signal arrive receiver, implements ...

Multitone Jamming Rejection of Frequency Hopped OFDM Systems in Wireless Channels
2012 IEEE Vehicular Technology Conference (VTC Fall), 2012This work considers the bit error rate (BER) performance of orthogonal frequency division multiplexing (OFDM) frequency hopping (FH) systems in the presence of Multitone jamming (MTJ) and multipath fading. Analytical and simulation results confirmed that optimum jamming strategies require channel and signal power side information.

Multitone jamming rejection of FFH/BFSK self-normalizing receiver
IEEE Military Communications Conference. Proceedings. MILCOM 98 (Cat. No.98CH36201), 2002A computationally efficient bit-error rate (BER) expression for a fast frequency-hopped binary frequency shift-keying (FFH/BFSK) spread-spectrum (SS) communication system is derived based on Taylor-series expansion. The FFH system employs a soft-decision self-normalizing receiver against the worst-case multitone jamming (MTJ) and additive white ...

Performance of Differential Frequency Hopping System under Multitone Jamming
2006 Asia-Pacific Conference on Communications, 2006Differential Frequency Hopping (DFH) is a novel technique for the frequency-hopping system in HF (High Frequency) bands. The frequency transition function (FTF) and the signal detection methods are the key issues for DFH system. Symbol-by-symbol detection and sequence detection are adopted in DFH system.
