We derive the analytical bit-error rate (BER) expressions for a fast frequency-hopped binary frequency-shift keying self-normalizing receiver over a fading channel with the worst-case band multitone jamming (MTJ) and additive white Gaussian noise (AWGN).

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

Performance analsis of hybrid DS-SFH/MSK spread-spectrum system under multitone jamming
MILCOM 1999. IEEE Military Communications. Conference Proceedings (Cat. No.99CH36341), 2003This paper studies the performance of a hybrid DS-SFH signal in the presence of partial band multitone jamming and AWGN. MSK is employed as FH spread spectrum modulation. The DS spread signal bandwidth is equal to the FH slot spacing. An equation for the BER is developed. Performance is evaluated, assuming a worst case jammer strategy.

Hybrid spread spectrum signal acquisition in the presence of worst case multitone jamming
MILCOM 97 MILCOM 97 Proceedings, 2002The acquisition performance of a hybrid slow frequency hopped direct sequence spread spectrum (SFH/DS SS) communication link in the presence of multitone jamming is analysed. Equations are derived to enable analysis of the optimisation of the jamming strategy. It is shown that the jamming strategy may be optimised by varying the number of tones.

Performance of frequency hopped MSK signals in multitone jamming and additive white Gaussian noise
IEEE Conference on Military Communications, 2002Because of advantageous spectral properties, coherent minimum shift keying (MSK) is attractive for electronic counter-counter measures (ECCM) systems where high data throughput is required. These high rate ECCM systems typically use frequency-hopped (FH) spread-spectrum techniques to enhance antijam capabilities. The performance of MSK signals combined

MILCOM 91 - Conference record, 2002
A technique recently devised for diversity combining is used to detect the presence of a burst of continuous wave (CW) synchronization probes in a fast frequency-hopped communication system. Often noise samples from unused channels are used to generate interference statistics to ensure a low false alarm rate.

Performance analysis of FH/DPSK in additive white Gaussian noise (AWGN) and multitone jamming
MILCOM 88, 21st Century Military Communications - What's Possible?'. Conference record. Military Communications Conference, 2003The author analyzes the bit error rate (BER) performance of frequency-hopping differential phase-shift keying (DPSK) in additive white Gaussian noise (AWGN) and multitone jamming. It is shown that the exact BER is given by a compact expression in terms of Marcum's Q-function.

Acquisition performance of a hybrid SFH/DS spread spectrum link in the presence of multitone jamming
Proceedings of ICICS, 1997 International Conference on Information, Communications and Signal Processing. Theme: Trends in Information Systems Engineering and Wireless Multimedia Communications (Cat. No.97TH8237), 2002An acquisition system for a hybrid frequency hopped direct sequence spectrum communication link is proposed and its performance in the presence of multitone jamming is analysed. Given a certain power, the multitone jammer can optimise its effectiveness by varying the number of jammed hop slots. It is shown that the number of jamming tones which results
