Flame propagation in a gasification channel [PDF]

open access: yesEnergy, 2010
In the present study, propagation of a gasification flame through a coal channel is considered. A simplified physical model incorporating all of the main physical factors determining the flame front propagation in a gasification reactor is suggested. It is demonstrated that the flame propagation is governed by the energy balance in the channel.

Exploring symmetry in wireless propagation channels [PDF]

open access: yes2017 European Conference on Networks and Communications (EuCNC), 2017
Wireless communications literature is very rich with empirical studies and measurement campaigns that study the nature of the wireless propagation channel. However, despite their undoubted usefulness, many of these studies have omitted a fundamental yet key feature of the physical signal propagation, that is, wireless propagation asymmetry.

Models for MIMO propagation channels: a review [PDF]

open access: yesWireless Communications and Mobile Computing, 2002
AbstractThis paper reviews recently published results on multiple input multiple output (MIMO) channel modeling. Both narrowband and wideband models are considered. We distinguish between two main approaches to MIMO channel modeling, that is, physically based and nonphysically based modeling.

A survey on vehicle-to-vehicle propagation channels [PDF]

open access: yesIEEE Wireless Communications, 2009
Traffic telematics applications are currently under intense research and development for making transportation safer, more efficient, and more environmentally friendly. Reliable traffic telematics applications and services require vehicle-to-vehicle wireless communications that can provide robust connectivity, typically at data rates between 1 and 10 ...

Propagation Measurements and Estimation of Channel Propagation Models in Urban Environment [PDF]

open access: yesKSII Transactions on Internet and Information Systems, 2017
Wireless communication is a telecommunication technology, which enables wireless transmission between the portable devices to provide wireless access in all types of environments. In this research, the measurements and various empirical models are analysed and compared in order to find out a suitable propagation model to provide guidelines for cell ...

Expectation Propagation for Flat-Fading Channels

open access: yesIEEE Wireless Communications Letters, 2023
This letter addresses the problem of signal detection in flat-fading channels. In this context, receivers based on the expectation propagation framework appear to be very promising although presenting some critical issues. We develop a new algorithm based on this framework where, unlike previous works, convergence is achieved after a single forward ...

A Global Perspective on Inflation and Propagation Channels [PDF]

open access: yesSSRN Electronic Journal, 2012
This paper revisits the evidence on monetary policy transmission. It extends the existing literature in three dimensions. First, we attempt to internalise potential international channels of transmission by taking a global perspective. More specifically, we explore global aggregates covering a broader set of countries (ca.

Propagation measurements and models for wireless communications channels [PDF]

open access: yesIEEE Communications Magazine, 1995
The authors describe the type of signals that occur in various environments and the modeling of the propagation parameters. Models are essentially of two classes. The first class consists of parametric statistical models that on average describe the phenomenon within a given error. They are simple to use, but relatively coarse.
