In order to achieve adaptive channel coding and adaptive modulation, the main causes of degradation to system performance are the decoder selection error and modulator estimation error. The utilization of supplementary information, in an estimation system utilizing channel estimation results, blind modulation estimation, and blind encoder estimation using several decoders information and encode...

Motivated by a problem considered earlier by Schrodinger [1]{[2], Jamison [3]{[4] and others, we examine in this paper the construction of Gauss-Markov processes with xed reciprocal dynamics. Given the class of reciprocal processes speci ed by a second-order model, a procedure is described for constructing a Markov process in the class with preassigned marginal probability densities at the end...

Navigation through the web, colloquially known as “surfing”, is one of the main activities of users during web interaction. When users follow a navigation trail they often tend to get disoriented in terms of the goals of their original query and thus the discovery of typical user trails could be useful in providing navigation assistance. Herein we give a theoretical underpinning of user navigat...

In this paper we provide an extensive overview of Hidden Markov models for longitudinal data. It is a stochastic model used to describe the evolution of observable events that depends on internal factors which are not directly observable. We will illustrate the general version of the model and the estimation procedures and the more interesting extensions for social sciences like the inclusion o...

This paper discusses efficient solutions to large-scale two-dimensional estimation problems, using reducedstate methods motivated by the multipole method of mathematical physics. The work is mainly exploratory, building on past efforts in multiscale statistical signal modeling and estimation. We will illustrate applications to the estimation of Markov random field textures, with the motivation ...

This paper is about multiple-F0 tracking and the estimation of the number of harmonic source streams in music sound signals. A source stream is understood as generated from a note played by a musical instrument. A note is described by a hidden Markov model (HMM) having two states: the attack state and the sustain state. It is proposed to first perform the tracking of F0 candidates using a high-...
