VCR-LFM-BPSK signal design for countering advanced interception technologies

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...

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...

Advanced technologies for LTE advanced

With the explosive growth in mobile data traffic fueled by smartphones and mobile applications, transition from the 3rd generation (3G) toward 4th generation (4G) cellular networks is progressing at an unprecedented pace. Since the first release (release 8) of the 3rd generation partnership project (3GPP) long-term evolution (LTE) standard in December 2008, LTE has become the de facto standard ...

Design of Optimum Weighting Functions for LFM Signals

Linear frequency-modulated (LFM) pulse signals are probably the most common type of pulse compression waveforms for various radar systems (Barton, 2005; Cook&Bernfeld, 1967; Curlander & McDonough, 1991; Levanon & Mozeson, 2004; Richards, 2005; Skolnik, 2008). LFM signals are also often the waveform of choice for wideband systems, where the required bandwidth may be hundreds of megahertz. The am...
