“…The Nyquist Folding receiver (NYFR) and the reconfigurable direct radio frequency bandpass sampling receiver (RDRFBSR) were invented by Fudge [3,4] who showed that the entire analog bandwidth could be folded into one Nyquist zone using one analog-to-digital converter (ADC) by marking the different frequency zones with dependent frequency modulations. This approach reduces the number of ADCs considerably, and we can recover the signal from the output of the NYFR in a sparse environment.…”

Abstract: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 digital channelized receiver (DCR).

Abstract-Nyquist folding receiver (NYFR) is a new kind of interception architecture, which can simultaneously intercept wideband signals in multi-Nyquist zones with one or two analog-to-digital converters (ADCs). A parameter estimation algorithm of the linear frequency modulated (LFM) signal intercepted by an improved NYFR is presented. Firstly, the NYFR is improved by introducing a synchronous mechanism, and we denote this structure as a synchronous NYFR (SNYFR). Secondly, taking LFM as an example, the input and output noise distributions of an SNYFR are discussed. Then, a fast parameter estimation algorithm is derived from the frequency spectrum of the output signal, and an advice for the design of local oscillator signal is given. Simulations show that the parameter estimation accuracy is close to the maximum likelihood when the signal to noise ratio (SNR) is above −3 dB.

“…Another efficient analogy-to-information (A2I) architecture is called the NYFR [5] in 2006 presented, which folds the broadband radio frequency (RF) input by sub-sampling with a stream of short pulses. The modulation sampling induces a bandwidth widening that varies with the Nyquist zone (NZ, i.e.…”

Abstract. The Nyquist Folding Receiver (NYFR) is an efficient analogy-to-information (A2I) architecture that folds the broadband RF inputs by subsampling so that can sample with a low-speed ADC. The compressive sensing (CS) model of the NYFR can be built in the sparse environment to recover by traditional CS algorithms. This paper presents an improved algorithm SAMP-SVD based on sparsity adaptive matching pursuit (SAMP) and singular value decomposition (SVD) which is intended to deal with the problem caused by SAMP recovering-the inversion of matrix, avoiding the problem of whether matrix is singular and reducing the time of computation. A comparative analysis between the presented method and sparse reconstruction by separable approximation (SpaRSA) is discussed; simulation results show the algorithm can reconstruct the signal effectively and estimate the frequencies accurately.
