Intercept of Frequency Agility Signal using Coding Nyquist Folding Receiver

The parameter estimation of the frequency agility (FA) signal using the coding Nyquist folding receiver (CNYFR) is presented. The estimation algorithm adopting linear frequency modulation (LFM) as the local analogue modulation is derived. The Nyquist zone is estimated by the pseudo Wigner-Ville distribution (PWVD) and the hopping frequencies are calculated by the maximum likelihood (ML) method....

Nyquist folding digital receiver for signal interception

A new architecture, denoted as the Nyquist folding digital receiver (NYFDR), to compress the data for signal interception is presented. The NYFDR is a digital version of the Nyquist folding receiver (NYFR). Simulation results show that the NYFDR has advantages over NYFR in the detection of Nyquist zone. Moreover, the data rate and resource consumption of the NYFDR are less than those of the dig...

A parameter estimation algorithm for LFM/BPSK hybrid modulated signal intercepted by Nyquist folding receiver

Nyquist folding receiver (NYFR) is a novel ultra-wideband receiver architecture which can realize wideband receiving with a small amount of equipment. Linear frequency modulated/binary phase shift keying (LFM/BPSK) hybrid modulated signal is a novel kind of low probability interception signal with wide bandwidth. The NYFR is an effective architecture to intercept the LFM/BPSK signal and the LFM...

A Simplified Sub-Nyquist Receiver Architecture for Joint DOA and Frequency Estimation

Joint estimation of carrier frequency and direction of arrival (DOA) for multiple signals has been found in many practical applications such as Cognitive Radio (CR). However, Nyquist sampling mechanism is costly or implemented due to wide spectrum range. Taking advantage of sub-Nyquist sampling technology, some array receiver architectures are proposed to realize joint estimation of carrier fre...
