Alternative Awaiting and Broadcast for Two-Way Relay Fading Channels [PDF]

open access: yes, 2012
We investigate a two-way relay (TWR) fading channel where two source nodes wish to exchange information with the help of a relay node. Given traditional TWR protocols, transmission rates in both directions are known to be limited by the hop with lower ...

Neural field models with transmission delays and diffusion [PDF]

open access: yesThe Journal of Mathematical Neuroscience, 2020
AbstractA neural field models the large scale behaviour of large groups of neurons. We extend previous results for these models by including a diffusion term into the neural field, which models direct, electrical connections. We extend known and prove new sun-star calculus results for delay equations to be able to include diffusion and explicitly ...

Reverberating activity in a neural network with distributed signal transmission delays [PDF]

open access: yes, 2007
It is known that an identical delay in all transmission lines can destabilize macroscopic stationarity of a neural network, causing oscillation or chaos.

Geometric Scattering in Robotic Telemanipulation [PDF]

open access: yes, 2002
In this paper, we study the interconnection of two robots, which are modeled as port-controlled Hamiltonian systems through a transmission line with time delay. There will be no analysis of the time delay, but its presence justifies the use of scattering

A quantitative analysis and performance study of fast congestion notification (FN) mechanism [PDF]

open access: yes, 2009
Congestion in computer network happens when the number of transmission requests exceeds the transmission capacity at a certain network point (called a bottle-neck resource) at a specific time.

Source-Channel Coding under Energy, Delay and Buffer Constraints [PDF]

open access: yes, 2014
Source-channel coding for an energy limited wireless sensor node is investigated. The sensor node observes independent Gaussian source samples with variances changing over time slots and transmits to a destination over a flat fading channel.

Transmission time delays organize the brain network synchronization [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2019
The timing of activity across brain regions can be described by its phases for oscillatory processes, and is of crucial importance for brain functioning. The structure of the brain constrains its dynamics through the delays due to propagation and the strengths of the white matter tracts. We use self-sustained delay-coupled, non-isochronous,

Frame delay and loss analysis for video transmission over time-correlated 802.11A/G channels [PDF]

open access: yes, 2007
This paper presents simulation results for the transmission of unicast MAC frames over 802.11a/g. Fading channel models at various Doppler frequencies are developed to generate time- correlated SNR waveforms.
