This paper is concerned with the fixed-interval smoothing estimation for time-delay systems which include continuous-time case and discrete-time case. In the case of discrete-time systems, the problem can be solved by using the conventional state augmentation approach. However, this approach is not suitable for the continuous-time case. In this paper, we will propose a unified approach...
This paper is concerned with the optimal filter problems for networked systems with random transmission delays, while the delay process is modeled as a multi-state Markov chain which incorporates the data losses naturally. By defining an indicator function of the random delay, the optimal filter problems are transformed into the ones of the standard Markov jumping parameter measurement system. We...
In this paper, we will consider the problems where observation delay is time-varying and design distributed estimators by combining a consensus strategy. The optimal local estimator for every node with time-varying observation delay is first designed, which plays an important role in the distributed estimator design. Then the optimal distributed estimator for any choice of the consensus gain is proposed...
Time Based (TB) localization in terrestrial communications mobile radio as a complementation to global navigation satellite systems has gained recently plenty of interests. As an essential tool to develop suitable algorithms for joint communications and localizations in mobile radio networks, the wireless channel model has a growing significance. For both communications and localizations, the time...
