报告摘要：
In this talk, we present some recent works in remote state estimation of a linear Gaussian system. In particular, our focus is on two aspects of remote estimation: packet dropping and sensor scheduling. We start by giving an overview of some existing results on estimation over a packet-dropping network. This is followed by a discussion on sensor scheduling and an introduction of both offline and online sensor schedules, the latter of which is also known as event-based sensor schedules. We show that the offline schedules and some well-designed event-based schedules preserve the Gaussianity of the system. When scheduling the sensor transmission over a packet-dropping network, we show that it is not possible to design any event-based schedules, except the offline ones, which can preserve the Gaussianity of the system.
