Spike sorting at sub-Nyquist rates [PDF]
2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012 Spike sorting relies on the ability to establish the temporal occurrence of action potentials and their relation to specific neurons. Neural information is intrinsically compressible and as such suitable for sparse sampling. Potentially, this should allow for the use of multi-channel recordings, which is particularly advantageous to improve spike ...

Wideband spectrum sensing based on advanced sub-Nyquist sampling structure
EURASIP Journal on Advances in Signal Processing, 2022 As the bandwidth increases, the high-speed sampling rate becomes the bottleneck for the development of wideband spectrum sensing. Wideband spectrum sensing with sub-Nyquist sampling attracts more attention and modulated wideband converter (MWC) is an ...

Sub-Nyquist Sampling OFDM Radar
IEEE Transactions on Radar Systems, 2023 In this paper, we propose a sub-Nyquist sampling (SNS) orthogonal frequency-division multiplexing (OFDM) radar system capable of reducing the analog-to-digital converter (ADC) sampling rate in OFDM radar without any additional manipulations of its hardware and waveform.

Towards sub-nyquist cognitive radar [PDF]
2016 IEEE Radar Conference (RadarConf), 2016 Cognitive radar (CR) has recently been considered as a natural next step for traditional radar. The cognitive property assumes both transmitter and receiver to be able to dynamically adapt to environment changes. In this work, we propose to exploit sub-Nyquist sampling methods that have been originally proposed to reduce the sampling rate bottleneck at
