## Abstract This paper proposes an errorโcorrection algorithm for channel error using the hidden Markov model (HMM). The proposed method uses two probabilities calculated by the information source model (HMM) and the channel model, under the constraint of the received code sequence, and estimates t

โฆ Synopsis
Abstract
This paper considers Markov errorโcorrection (MEC) models in which deviations from the longโrun equilibrium are characterized by different rates of adjustment. To motivate our analysis and illustrate the various issues involved, our discussion is structured around the analysis of the longโrun properties of US stock prices and dividends. It is shown that the MEC model is flexible enough to account for situations where deviations from the longโrun equilibrium are nonstationary in one of the states of nature and allows us to test for such a possibility. An empirical specification procedure to establish the existence of MEC adjustment in practice is also presented. This is based on a multiโstep test procedure that exploits the differences between the global and local characteristics of systems with MEC adjustment. Copyright ยฉ 2004 John Wiley & Sons, Ltd.
