Data Transmission over Networks for Estimation
نویسندگان
چکیده
In this paper, we consider the following problem. Suppose a sensor is taking measurements of a dynamic process. It needs to communicate the information to an estimator over a network of communication links that can drop packets stochastically. What is the optimal processing at each node in the network that allows the estimator to estimate the state of the process? We provide a strategy that yields the optimal estimation performance in the minimum mean squared sense while requiring only a constant amount of memory and processing at each node. We also provide conditions on the network for the estimate error covariance to be stable under this algorithm. Keywords— Estimation across Networks, Optimal Estimation, Encoding of Information

متن کاملروشی جدید برای اختفای خطا در فریم‌های ویدئو با استفاده از شبکه عصبی RBF
Transmission of compressed video over error prone channels may result in packet losses, which can degrade the image quality. Error concealment (EC) is an effective approach to reduce the degradation caused by the missed information. The conventional temporal EC techniques are always inefficient when the motions of the video object are irregular. In this paper, in order to overcome this problem,...
