On tractable wireless channel models
Ninth IEEE International Symposium on Personal, Indoor and Mobile Radio Communications (Cat. No.98TH8361), 2002We present techniques to capture the behavior of realistic channels with mathematically tractable models, We examine different state-space aggregation techniques to reduce a large number of states of Markov chain to a fewer number of states, The property of strong and weak lumpability is discussed and the stochastic bounding techniques are examined ...

A multipath model for the powerline channel
IEEE Transactions on Communications, 2002The development of powerline communication (PLC) systems for Internet, voice, and data services requires measurement-based models of the transfer characteristics of the mains network suitable for performance analysis by simulation. This paper presents an analytic model describing complex transfer functions of typical powerline networks using only a ...

Modeling wireless channel fading
IEEE 54th Vehicular Technology Conference. VTC Fall 2001. Proceedings (Cat. No.01CH37211), 2002We compare measured fading data with the popular Rayleigh model. Our results show that this model does not agree with the experimental data. As an alternative, we approximate the experimental data using autoregressive moving average (ARMA) models. To validate the models, we compare several characteristics of fading obtained analytically, by simulation,

Na(+)- and Ca2(+)-channel blockers behave as electron donors in reactions with excited dye radicals, while agonists of these channels behave as electron acceptors in the same reactions. The opposite redox characteristics of channel blockers and agonists may reflect their opposite action on the channels.

Modeling Voltage-Dependent Channels
2009This chapter describes the voltage-gated ion channels. It considers the different types of formalisms in modeling ionic currents as the action potential and voltage-clamp recordings of the T-type calcium current in thalamic neurons. The chapter specifically reviews the voltage-clamp behavior of the sodium channel and the genesis of action potentials ...

MIMO Propagation Channel Modeling
IEICE Transactions on Communications, 2005This paper provides an overview of research in channel modeling for multiple-input multiple-output (MIMO) data transmission focusing on a radio wave propagation. A MIMO channel is expressed as an equivalent circuit with a limited number of eigenpaths according to the singular-value decomposition (SVD).
