A hardware prototype of sub‐Nyquist radar with unknown pulses
Electronics Letters, 2021 In a conventional radar system, the hardware cost increases with the sampling rate of the receiver. Sub‐Nyquist radar systems operate at lower sampling rates and hence reduce the hardware cost and complexity. A sub‐Nyquist radar system uses the knowledge

Sub-Nyquist Sampling in Shift-Invariant Spaces
2020 28th European Signal Processing Conference (EUSIPCO), 2021 We introduce a novel framework for acquisition of analog signals by combining compressive sensing (CS) and the shift-invariant (SI) reconstruction procedure. We reinterpret the random demodulator as a system that acquires a linear combination of the samples in the conventional SI setting with the box function as the sampling kernel.

Channel Capacity Under Sub-Nyquist Nonuniform Sampling [PDF]
IEEE Transactions on Information Theory, 2014 This paper investigates the effect of sub-Nyquist sampling upon the capacity of an analog channel. The channel is assumed to be a linear time-invariant Gaussian channel, where perfect channel knowledge is available at both the transmitter and the receiver.

Low Complexity Sub-Nyquist Wideband Spectrum Sensing for Cognitive Radio
IEEE Access, 2018 In order to provide more available spectrum and quickly switchover, wideband spectrum sensing (WSS) is desirable for cognitive radio. Sub-Nyquist sampling is crucial for WSS to reduce energy and computational costs, while the existing algorithms based on
