Abstract

This paper considers the state estimation of hidden Markov models (HMMs) in a network of sensors which communicate with the fusion center via finite symbols by fading channels. The objective is to minimize the long term mean square estimation error for the underlying Markov chain. By using feedback from the fusion center, a dynamic quantization scheme for the sensor nodes is proposed and analyzed by a Markov decision approach. The performance improvement by feedback, as well as the effect of fading, is illustrated.
