Performance analysis of frequency hopped/coherent MPSK in the presence of multitone jamming
IEEE Transactions on Communications, 1996This paper studies the performance of frequency hopped/coherent M-ary PSK signals in the presence of partial-band multitone jamming. The probability density function for the jammed received signal phase is found and utilized in obtaining a probability of error expression.

Error probabilities and performance comparisons of various FFH/MFSK receivers with multitone jamming
IEEE Transactions on Communications, 2005Analytical bit-error-rate (BER) expressions are derived for various fast frequency-hopped (FFH) M-ary frequency-shift-keying receivers with the worst-case multitone jamming and additive white Gaussian noise. The BER results for different receivers are compared and the effects of the optimum diversity level on BER performance are also presented.

Multitone jamming rejection of FFH/BFSK spread-spectrum system over fading channels
IEEE Transactions on Communications, 1998Analytical expressions for bit-error probability are derived for a fast frequency-hopping binary frequency-shift keying (FFH/BFSK) spread-spectrum communication system over a fading channel with worst-case band multitone jamming (MTJ) and additive white Gaussian noise (AWGN).

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 ...

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.

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)
