Multitone jamming rejection of FFH/BFSK self-normalizing receiver

open access: closedIEEE Military Communications Conference. Proceedings. MILCOM 98 (Cat. No.98CH36201), 2002
A 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 ...

Anti-Jam Performance of Fast Frequency Hopped MFSK with Coding against Worst-Case Multitone Jamming

open access: closedMILCOM 1987 - IEEE Military Communications Conference - Crisis Communications: The Promise and Reality, 1987
Fast frequency hopped (FFH) MFSK with coding can significantly improve anti-jam (AJ) performance against partial band jamming. Multitone (MT) jamming has been shown to be the most effective partial band jamming technique, particularly against higher order M-ary FSK modulation.

Performance analysis of an FFH/BFSK product-combining receiver with multitone jamming over Rician-fading channels

open access: closedIEEE Transactions on Vehicular Technology, 2002
The performance of a fast frequency-hopped binary frequency-shift keying (FFH/BFSK) spread-spectrum (SS) communication system is studied in this paper. The FFH system employs a product-combining receiver against the worst case multitone jamming (MTJ) and additive white Gaussian noise (AWGN). The compact characteristic functions of the natural logarithm

Error performance analysis of FFH-MFSK with multitone jamming

open access: closedProceedings of 8th International Symposium on Personal, Indoor and Mobile Radio Communications - PIMRC '97, 2002
An 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.

The performance of low density parity check coded FFH systems under multitone jamming

open access: closed2011 International Conference on Computer Science and Service System (CSSS), 2011
Fast 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 ...

Multitone Jamming Rejection of Frequency Hopped OFDM Systems in Wireless Channels

open access: closed2012 IEEE Vehicular Technology Conference (VTC Fall), 2012
This 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.
