Theory for the Accuracy of Microcomb Photonic Microwave Transversal Signal Processors [PDF]
IEEE Journal of Selected Topics in Quantum Electronics (JSTQE)
Volume 29 (2023), 2023 Photonic RF transversal signal processors, which are equivalent to reconfigurable electrical digital signal processors but implemented with photonic technologies, have been widely used for modern high-speed information processing. With the capability of generating large numbers of wavelength channels with compact micro-resonators, optical microcombs ...

Rotating Interferometer-based Algorithm for Parameter Estimation of Near-field Source
Leida xuebao, 2015 This paper proposes a novel rotating interferometer-based algorithm for parameter estimation of nearfield source. The algorithm exploits the rotation of a single long baseline interferometer and the integration operation of the phase to unwrap the phase ...

Graphon Signal Processing [PDF]
IEEE Transactions on Signal Processing, 2020 Graphons are infinite-dimensional objects that represent the limit of convergent sequences of graphs as their number of nodes goes to infinity. This paper derives a theory of graphon signal processing centered on the notions of graphon Fourier transform ...

Reversible Joint Hilbert and Linear Canonical Transform Without Distortion [PDF]
IEEE Transactions on Signal Processing, Volume 61, Issue 19,
Oct.1, 2013, 2017 Generalized analytic signal associated with the linear canonical transform (LCT) was proposed recently by Fu and Li ["Generalized Analytic Signal Associated With Linear Canonical Transform," Opt. Commun., vol. 281, pp. 1468-1472, 2008]. However, most real signals, especially for baseband real signals, cannot be perfectly recovered from their ...
