Abstract--We consider cooperative spectrum sensing for cognitive radios. We develop an energy efficient detector with low detection delay using sequential hypothesis testing. Seque...
Novel experimental characterization method and circuit modeling for frequency-variant transmission lines are presented. Experimental test patterns are designed and fabricated by u...
Static function hierarchies and models of the dynamic behaviour are typically used in e-commerce systems. Issues to be verifies are the completeness and correctness of the static f...
To improve the performance and wellbeing of humans in complex human-computer interaction settings, an interesting challenge for an ambient (or pervasive) agent system is to recogni...
For software executing several threads in parallel, testing is unreliable, as it cannot cover all thread schedules. Model checking, however, can cover all possible thread interlea...
