DOI: 10.1007/s11128-020-02644-2
Abstract: We propose the protocol for noise-resilient frequency synchronization (syntonization) of distant clocks’ local oscillators through a distributed quantum network. The syntonization is performed in two steps; First, we identify the node undergoing the systematic shift… read more here.

DOI: 10.1080/00051144.2017.1372122
Abstract: ABSTRACT Many traditional grids have started to integrate the DC/AC inverters in their networks. This requires a good control to enhance the power quality. The grid frequency behaviour is one of the principal indicators that… read more here.

DOI: 10.1088/1361-6668/ac1d96
Abstract: We demonstrate the frequency synchronization of multiple single-flux quantum (SFQ) oscillators with different oscillation frequencies. To synchronize these SFQ oscillators, a common constant bias current is supplied to the SFQ oscillators without any bias resistors.… read more here.

DOI: 10.1109/lwc.2022.3214002
Abstract: In this letter, we propose timing offset (TO) and carrier frequency offset (CFO) estimators for orthogonal time frequency space modulation (OTFS). The proposed estimators do not require any additional training overheads as they deploy the… read more here.

DOI: 10.1109/tcns.2021.3128493
Abstract: We investigate the frequency stability of a high-order multi-converter system. For this, we identify its symmetry (i.e., rotational invariance) generated by a static angle shift and rotation of ac signals. We characterize the synchronous steady-state… read more here.
