The Performance of M-ary FH-DPSK in the Presence of Partial-Band Multitone Jamming
IEEE Transactions on Communications, 1982Using a geometric approach, the performance of M -ary FH-DPSK in the presence of partial-band multitone jamming is evaluated. The optimal jamming strategy is determined as a function of the number of signaling levels M and the ensuing results are used to determine worst case bit error probability performance as a function of this same parameter.

The performance of low density parity check coded FFH systems under multitone jamming
2011 International Conference on Computer Science and Service System (CSSS), 2011Fast frequency hopping (FFH) is a very effective way to combat jamming. In this paper, low density parity check (LDPC) code is combined with diversity-combining techniques to enhance the performance of FFH systems under band multitone jamming (BMTJ). The optimum maximum-likelihood (ML) combining which needs perfect side information (SI), and various ...

Minimax and generalized likelihood ratio test for noncoherent FH/BFSK in band multitone jamming
2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012We investigate non-coherent FH/BFSK detection in band multitone jamming when Bayesian detection is unfeasible due to lack of knowledge on a priori jamming state probabilities. We derive joint-suboptimal decision metrics of jamming states under Minimax hypothesis testing in band multitone jamming and AWGN. A sub-optimal generalized likelihood ratio test

This paper studies the bit-error rate (BER) performance of a fast frequency-hopped (FFH) binary frequency-shift-keying (BFSK) clipper receiver in the presence of multitone jamming (MTJ) and additive white Gaussian noise (AWGN). By using the Taylor-series expansion and the quantization approach, the BER expressions for higher diversity levels can be ...

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 ...
