“…In the presence of jamming, various diversity combining schemes have been proposed for noncoherent frequency shift keying (FSK) based FFH, including maximum likelihood (ML) combining [1][2][3][4][5][6][7], FFT based combining schemes [8], linear combining (LC) [9], self-normalization combining [10], noise-normalization combining [11], product combining [12][13][14][15][16][17], and clipped combining [18,19]. Among the noncoherent FFH/FSK combining schemes, ML combining yields the best BER performance in the presence of jamming.…”

Fast frequency hopping (FFH) is commonly used as an antijamming communication method. In this paper, we propose efficient adaptive jamming suppression schemes for binary phase shift keying (BPSK) based coherent FFH system, namely, weighted equal gain combining (W-EGC) with the optimum and suboptimum weighting coefficient. We analyze the bit error ratio (BER) of EGC and W-EGC receivers with partial band noise jamming (PBNJ), frequency selective Rayleigh fading, and channel estimation errors. Particularly, closed-form BER expressions are presented with diversity order two. Our analysis is verified by simulations. It is shown that W-EGC receivers significantly outperform EGC. As compared to the maximum likelihood (ML) receiver in conventional noncoherent frequency shift keying (FSK) based FFH, coherent FFH/BPSK W-EGC receivers also show significant advantages in terms of BER. Moreover, W-EGC receivers greatly reduce the hostile jammers' jamming efficiency.

“…It has been shown that the use of the selfnormalized receiver shown in Figure 1 can improve the worst case performances of a frequency-hopped BFSK signal under partial band jamming interference over a Rician channel [2]. In an analogous way, we seek to improve the performance of a DPSK system employing time diversity under pulse noise interference over a Rician channel.…”

The performance of a Direct Sequence Differential Phase Shifr Keying (DS-DPSK) spread spectrum system employing time diversity and self-normalization over a Rician frequency nonselective, slowly fading channel in the presence of pulsed noise inteverence and additive white Gaussian noise (A WGN) is considered. An inteverence model which considers the possibility that either both, one or none of the information bits experience jamming is employed. Worst case pe formance under severe and moderate fading conditions are analyzed. Results indicate that the self-normalized receiver is eflective in mitigating the effects of pulse noise jamming for all fading conditions considered.

SUMMARYThe bit error rate (BER) performance of a noncoherent fast frequency-hopped binary orthogonal frequencyshift-keying (FFH/BFSK) spread spectrum (SS) receiver with adaptive gain control (AGC) is investigated in the presence of partial-band jamming (PBJ) and additive white Gaussian noise (AWGN) over frequency nonselective slow Nakagami-fading channels. Exact BER expressions in a onefold integral is derived. The effects of arbitrarily values of fading parameter and diversity level on system performance are considered. Numerical results compare the worst-case BER performance of the AGC receiver with that of the product combining (PC) receiver.
