Joint data QR-detection and Kalman estimation for OFDM time-varying Rayleigh channel complex gains
—This paper deals with the case of a high speed mobile receiver operating in an orthogonal-frequency-divisionmultiplexing (OFDM) communication system. Assuming the knowledge of d...

On the decidability and complexity of Metric Temporal Logic over finite words
Abstract. Metric Temporal Logic (MTL) is a prominent specification formalism for realtime systems. In this paper, we show that the satisfiability problem for MTL over finite tim...

Parameterized computational complexity of Dodgson and Young elections
We show that the two NP-complete problems of Dodgson Score and Young Score have differing computational complexities when the winner is close to being a Condorcet winner. On the ...
