Global navigation satellite system has been widely used, but it is vulnerable to jamming. In
military satellite communications, frequency hopping (FH) signal is usually used for anti …

The lack of sufficient spectral resources in many alternative positioning, navigation, and
timing (APNT) systems for aviation has led to the problem of mutual interferences. Building …

To improve the anti-interference performance and mitigate the autocorrelation function
(ACF) ambiguity of dual-frequency multiplexing modulation, we propose a new type of …

Abstract Fast Frequency Hopping (FFH) communications is an important technology of anti-
jamming in military applications. In this paper, anti-jamming performance and …

In this paper, we propose a possibility of usage of carrier superpositioning scheme for a
specific slow frequency hopping (SFH) transmission method for the satellite data link in …

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

The Coherent Fast Frequency Hopping (CFFH) technique can improve the anti-jamming
ability of wireless communication, and the digital local oscillator whose signal is completely …

Multicarrier phase ranging (MCPR) technique has been widely used in radio navigation,
telemetry, radar, and many other fields. In an MCPR system, unique range estimation can be …

With the development of navigation satellite constellation systems, to improve navigation
service and orbit determination performance, the accuracy requirements for maintaining …

In this paper, we analyze the bit error ratio (BER) of fast frequency hopping (FFH) system
with binary phase shift keying (BPSK) in high-mobility wireless channels. By taking into …
