Bajaj, V. (author), Van de Plas, Raf (author), Wahls, S. (author)While probabilistic constellation shaping (PCS) enables rate and reach adaption with finer granularity [1] (Cho and Winzer, 2009), it imposes signal processing challenges at the receiver. Since the distribution of PCS-quadrature amplitude modulation (QAM) signals tends to be Gaussian, conventional blind polarization demultiplexing algorithms...journal article 2024

Bajaj, V. (author), Buchali, Fred (author), Chagnon, Mathieu (author), Wahls, S. (author), Aref, Vahid (author)High-symbol-rate coherent optical transceivers suffer more from the critical responses of transceiver components at high frequency, especially when applying a higher order modulation format. Recently, we proposed in [20] a neural network (NN)-based digital pre-distortion (DPD) technique trained to mitigate the transceiver response of a 128...journal article 2022

Ianovskyi, F. (author), Prokopenko, Igor (author), Pitertsev, Alexander (author), Rhee, Huinam (author), Dmytruk, Anastasiia (author)This paper proposes generalized mathematical model of different passive interferences and develops an effective algorithm of digital signal processing for detection on the background of them. Models of interferences as random process of K-distribution is used with parametrization for the unwanted reflections from atmosphere, land, and sea....conference paper 2022

de Koster, P.B.J. (author), Wahls, S. (author)Efficient fiber-optic communication requires precise knowledge of the fiber coefficients, but these often change over time due to factors such as aging or bending. We propose a novel algorithm that identifies the average second-order dispersion and Kerr nonlinearity coefficient of a fiber, without employing any special training signals....journal article 2020

Wolszczak, W.W. (author)In many aspects measurement of the α/β ratio has advantages over other methods. It provides higher precision and higher density of excitation than is available with Compton or photoelectric effect electrons. It has been shown that the α/β ratio follows the same trends and patterns as previously found for nonproportionality of electron/ gamma...doctoral thesis 2019
