Super-Resolution Of Periodic Signals From Short Sequences Of Samples

ICASSP 2021accepted

Reconstruction of undersampled periodic signals of unknown period is an important signal processing operation. It is especially difficult operation when the sequences of samples are short and no information on the inter-sequence time distances is given. For such a case, there exist some algorithms t…

Triggerless Random Interleaved Sampling

Marek W. Rupniewski

ICASSP 2020accepted

A single short sequence of samples taken at sub-Nyquist rate rarely allows for periodic signal recovery. If there is more than one such sequence and time offsets between these sequences are given, the signal approximation is possible and is known as equivalent time or interleaved sampling. If the in…
