Behavior of Cascaded Binary Symmetric Channel for different number of cascades

2020 Fourth International Conference on I-SMAC (IoT in Social, Mobile, Analytics and Cloud) (I-SMAC), 2020
A Binary Symmetric Channel is a communication model that transmits bits of information through the channel. The transmission is governed by the error probability of the channel. Network routes require multiple links which can be realized using cascaded channels. A single equivalent channel for a series of the identical cascaded binary symmetric channel

Substrate channelling as an approach to cascade reactions

Nature Chemistry, 2016
Millions 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 ...

Cascaded Double Beaulieu-Xie Fading Channels

IEEE Communications Letters, 2020
In 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 ...

Mechanisms and Effects of Substrate Channelling in Enzymatic Cascades

2021
Substrate or metabolite channelling is a transfer of intermediates produced by one enzyme to the sequential enzyme of a reaction cascade or metabolic pathway, without releasing them entirely into bulk. Despite an enormous effort and more than three decades of research, substrate channelling remains the subject of continuing debates and active ...

Cascaded Fluctuating Two-Ray Fading Channels

IEEE Communications Letters, 2019
In this letter, we derive the exact probability density function (PDF), cumulative distribution function (CDF), and generalized moment generating function of a product of $N$ independent fluctuating two-ray (FTR) random variables. Capitalizing on the derived expressions, new expressions for the PDF and CDF of the FTR fading model, i.e., $N=1$

LDPC codes for the cascaded BSC-BAWGN channel

2009 47th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2009
We study the performance of LDPC codes over the cascaded BSC-BAWGN channel. This channel belongs to a family of binary-input, memoryless, symmetric-output channels, one that we call the {CBMSC(p, σ)} family. We analyze the belief propagation (BP) decoder over this channel by characterizing the decodable region of an ensemble of LDPC codes. We then give

Channel Prediction with Cascade AR Modeling

Advanced Int'l Conference on Telecommunications and Int'l Conference on Internet and Web Applications and Services (AICT-ICIW'06), 2006
Cascade autoregressive (AR) model with three parameters for any channel prediction order p is investigated. Although higher order AR model is better to get more precise future channel prediction profile, as the order of channel prediction goes higher, the number of channel prediction parameters we have to know is increased.

Automated Alignment Between Channel and Filter Cascade

Optical Fiber Communication Conference (OFC) 2019, 2019
We propose a new and cost-efficient method based on receiver-side spectrum monitoring to mitigate filter impairments. We experimentally demonstrated up to 3dB-reduction in filter penalties for 32GBd PDM-QPSK signals.

On the Performance of Cascaded Generalized K Fading Channels

GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009
A novel distribution referred to as N*generalized κ, constructed as the product of N statistically independent, but not necessarily identically distributed, generalized κ random variables (RVs) is introduced. Statistical characterization of the proposed distribution is carried out via the derivation of closed-form expressions for its moment generating,
