Hybrid Logics on Linear Structures: Expressivity and Complexity
We investigate expressivity and complexity of hybrid logics on linear structures. Hybrid logics are an enrichment of modal logics with certain first-order features which are algo...

A robust estimator and detector of circularity of complex signals
Recent research has revealed that circularity (or, propriety) of complex random signals can be exploited in developing optimal signal processors. In this paper, a robust estimator...

Low complexity least-squares filter design for the correction of linear time-varying systems
Abstract—In this paper, a low complexity algorithm for the design of a time-varying correction filter of finite impulse response (FIR) type is presented. Using the obtained fi...
