“…We also observe that the system corresponding to M = 16 achieves the lowest codeword error probability in both figures. It is well-known that the performance of the MFSK system in the absence of interference improves as M increases [5], whereas the detrimental effects of tone jamming on the performance of FH-MFSK increase as M is increased [6]. Moreover, in the context of the RS-coded system, using a higher value of M implies a high error correcting capability given by t = n−k 2 , when the code rate is a constant [5].…”

“…The transmitted signal is assumed to be interferred by a tone jamming signal consisting of Q equal-power continuous wave tones, each of which has a frequency equal to that of one of the M -ary signalling tones. We consider the case of n = 1-band multitone jamming (MTJ), which is regarded as the worst case tone jamming scenario [6]. In this context, the intentional jammer distributes the interfering tones in such a way that there is at most one interfering tone in an MFSK band, defined by the bandwidth occupied by the M FSK signalling tones.…”

“…We assume that the intentional jammer has explicit knowledge of the communication system's parameters and thus it is capable of adjusting the number of jamming tones accordingly, keeping the total MTJ power fixed. We can define the Signal to Jammer Power Ratio (SJR) as [6] …”

Abstract-The achievable performance of Reed Solomon (RS) coded slow frequency hopping (SFH) assisted M -ary frequency shift keying (MFSK) using various erasure insertion (EI) schemes is investigated, when communicating over uncorrelated Rayleigh fading channels in the presence of multitone jamming. Three different EI schemes are considered, which are based on the output threshold test (OTT), on the ratio threshold test (RTT) and on the joint maximum output-ratio threshold test (MO-RTT). The relevant statistics of these EI schemes are investigated mathematically and based on these statistics, their performance is evaluated in the context of error-and-erasure RS decoding. It is demonstrated that the system performance can be significantly improved by using error-and-erasure decoding invoking the EI schemes considered.

“…It has been shown that the band MTI gives poorer system performance. In [37], the author derived BER expressions for an FFH/MFSK LCR in terms of an exponentially tight Chernoff bound over non-fading channels. On the basis of the circularly symmetric function theory, Fourier-Bessel series and Fourier series, the expressions of the pdf and the cdf of the final decision statistic for an FFH/MFSK LCR were derived in [38] over a non-faded channel.…”

Over the past few decades, frequency hopping (FH) techniques have attracted considerable interest in both military and commercial communications. However, fading and interference can significantly degrade the performance of an FH system. One method commonly employed to overcome the degradation in performance because of the fading is the use of diversity. Furthermore, fast FH (FFH) systems can enjoy both time and frequency diversity and hence FFH systems employed in conjunction with diversity-combining techniques are effective for combating fading and interference effects. In this study, the authors provide a comprehensive survey on the past and current research work on diversity-combining techniques for suppressing different types of interference in FFH M-ary frequency-shiftkeying systems over various fading channels. Some commonly used theoretical approaches for analysing performance of FFH systems are also presented. In addition to the survey, they will also discuss some interesting areas of future work in this research topic.

Interference Suppression in Spread‐Spectrum Communication Systems

This chapter discusses interference excision techniques in spread spectrum communications systems. Both stationary and nonstationary interferers are considered. Sinusoidal, autoregressive, digital communication, and polynomial phase interference signals are effectively suppressed by different excision methods; each is suitable for one or more types of interferers. Time‐, frequency‐, and time‐frequency domain methods for analysis and estimation of the interference parameters are summarized. Domains other than time and frequency, such as the Gabor‐domain, the Wavelet‐domain, and quadratic time‐frequency signal representations, are appropriate for nontraditional smart jamming in which the interference parameters are highly dependent on time. Excision methods can be linear, bilinear, or nonlinear with performance dependent on the interference power relative to the desired signal and noise. In some cases, the slight performance enhancement offered by bilinear and nonlinear methods may not properly justify the increase in the algorithm complexity. The BER and receiver SINR expressions and curves are presented in this chapter for some of the key interference excision techniques.
