|Title:||Sub-Nyquist sampling of high-speed repetitive waveforms using compressed sensing|
|Keywords:||Compressed sensing (CS);Equivalent sampling frequency;Interleaved sampling;Signal reconstruction|
|Abstract:||This study presents a sub-Nyquist sampling model using compressed sensing (CS) as a new signal processing framework to acquire and reconstruct sparse signals. High-speed periodic signals were sampled using low frequency sampling circuit and reconstructed via CS recovery algorithm, resulting in a high equivalent sampling frequency. This prototype system is able to capture repetitive waveforms at an equivalent sampling rate of 2.5 GHz while sampling at no more than 50 MHz physically.|
