An exact closed-form expression of the characteristic function is derived for a fast frequency-
hopping (FFH) binary orthogonal frequency-shift-keying (FSK) spread-spectrum (SS) …

In modern warfare, the victory of electronic warfare has become one of the key factors
affecting the victory of war. It is an important part of electronic warfare that high-efficiency …

This paper proposes an integrated intelligent anti-jamming scheme for frequency hopping
(FH) system based on the modern signal processing, including the algorithms for jamming …

In Chapter 1, the basic philosophy of frequency hopping is introduced and two main types of
FH systems, namely slow frequency hopping (SFH) and fast frequency hopping (FFH) are …

Reactive symbol-level jammer has attracted attention due to its low energy cost and high
jamming efficiency. With the development of software-defined radio (SDR), the …

This paper considers spectrally efficient and robust wireless system design under malicious
jamming as well as unintentional interference. Due to limited spectrum and lack of a …

The performance of frequency hopping (FH) systems with M-ary frequency shift keying
(MFSK) modulation may be significantly degraded in the presence of a follower jammer. In …

We consider and investigate a generalized signaling method for non-coherent orthogonal
FH/BFSK in band multitone jamming (BMJ). We let symbol tones not be restricted within one …

It is difficult to ensure stability and communication efficiency of traditional anti-jamming
frequency hopping communication system in the frequency domain probabilistic jamming …

Frequency hopping systems have been widely used in military communications to prevent
hostile jamming, interception and detection. In traditional frequency hopping (FH) systems …
