Cascaded Double Beaulieu-Xie Fading Channels
IEEE Communications Letters, 2020In this letter, a mathematical characterization for the cascaded double Beaulieu-Xie (BX) fading model is presented. Exact and new expressions are determined for the probability density function (PDF) and for the cumulative distribution function (CDF) of the random variable that models the envelope of the cascaded double BX fading, and for the PDF and ...

The capacity of the cascaded fading channel in the low power regime
2014 IEEE Wireless Communications and Networking Conference (WCNC), 2014 In this paper, we present a simple way to compute the ergodic capacity of cascaded channels with perfect channel state information at both the transmitter and the receiver. We apply our generic results to the Rayleigh-double fading channel, and to the free-space optical channel in the presence of pointing errors and we express their low signal-to-noise

On The Capacity Of A Cascade Of Channels
Proceedings. 1991 IEEE International Symposium on Information Theory, 1993Summary: A class of information-theoretic problems is introduced that deal with systems in which information is transmitted through a series of noisy channels, with limited or no processing between channels. Some basic questions that arise in such systems are examined in detail.

Cluster Channeling in Cascade Reactions
The Journal of Physical Chemistry B, 2021Enzymatic cascade reactions, where a substrate is converted into a product in several steps, play a critical role in many biological systems. The enzymes in such reactions are often clustered inside intracellular compartments. To understand the effect of localization, we develop a theory for cascade reactions converting substrates into intermediates ...

Efficient Deep Learning-Based Cascaded Channel Feedback in RIS-Assisted Communications
IEEE Transactions on Vehicular TechnologyIn the realm of reconfigurable intelligent surface (RIS)-assisted communication systems, the connection between a base station (BS) and user equipment (UE) is formed by a cascaded channel, merging the BS-RIS and RIS-UE channels.

Cascading blockages in channel bundles
Physical Review E, 2015Flow in channel networks may involve a redistribution of flux following the blockage or failure of an individual link. Here we consider a simplified model consisting of N(c) parallel channels conveying a particulate flux. Particles enter these channels according to a homogeneous Poisson process and an individual channel blocks if more than N particles ...

Channel Estimation for Amplify-and-Forward Relaying: Cascaded Against Disintegrated Estimators
IET Communications, 2010 Due to copyright restrictions, the access to the full text of this article is only available via subscription.The authors investigate the performance of amplify-and-forward relaying with two different pilot-symbol-assisted channel estimation methods.

Cascade channels with infinite memory
2016 IEEE International Symposium on Information Theory (ISIT), 2016Two theorems are proved for a cascade channel with two components, one theorem regarding input memory and the other regarding output memory. First, we show that if both components are asymptotically input-memoryless, then the cascade channel is asymptotically input-memoryless as well.

Substrate channelling as an approach to cascade reactions
Nature Chemistry, 2016Millions of years of evolution have produced biological systems capable of efficient one-pot multi-step catalysis. The underlying mechanisms that facilitate these reaction processes are increasingly providing inspiration in synthetic chemistry. Substrate channelling, where intermediates between enzymatic steps are not in equilibrium with the bulk ...
