Linear time-invariant (LTI) systems are of fundamental importance in classical digital signal processing. LTI systems are linear operators commuting with the time-shift operator. For N-periodic discrete time series the time-shift operator is a circulant N × N permutation matrix. Sandryhaila and Moura developed a linear discrete signal processing framework and corresponding tools for datasets arising...
Suppose two finite signals are related by an unknown cyclic shift. Fast algorithms for finding such a shift or variants thereof are of great importance in a number of applications, e.g., localization and target tracking using acoustic sensors. The standard solution, solving shift finding by maximizing the cross-correlation between the two signals, may be rather efficiently computed using fast Fourier...
