Dispersive Optical Wireless Indoor Channels—From Frequency-Domain Modeling to Bit-Error-Rate Prediction

open access: yesIEEE Photonics Journal
Methods for calculating the impulse response of dispersive optical wireless channels have been known for a long time. However, a comprehensive procedure for predicting resulting bit error rates, starting from a highly accurate channel emulation method ...

On linear H∞ equalization of communication channels [PDF]

open access: yes, 2000
As an alternative to existing techniques and algorithms, we investigate the merit of the H∞ approach to the linear equalization of communication channels. We first give the formulation of all causal H∞ equalizers using the results of and then look at the

The collapse of cooperation in evolving games [PDF]

open access: yes, 2014
Game theory provides a quantitative framework for analyzing the behavior of rational agents. The Iterated Prisoner's Dilemma in particular has become a standard model for studying cooperation and cheating, with cooperation often emerging as a robust ...

Diversity techniques for blind channel equalization in mobile communications [PDF]

open access: yes, 1997
A blind algorithm for channel distortion compensation is presented which can be employed in spatial or temporal diversity receivers. The proposed technique can be used in frequency selective and frequency flat fading mobile channels, using burst ...

MIMO-OFDM System Performance and Parameter Estimations in Presence of Design Imperfections

open access: yesIEEE Access
Most of the MIMO-OFDM analyses in the literature assume idealized receiver conditions in terms of time and frequency synchronization, and sampling clock offset.

Robust Transmission in Downlink Multiuser MISO Systems: A Rate-Splitting Approach [PDF]

open access: yes, 2016
We consider a downlink multiuser MISO system with bounded errors in the Channel State Information at the Transmitter (CSIT). We first look at the robust design problem of achieving max-min fairness amongst users (in the worst-case sense). Contrary to the

A Generalized Two-Dimensional FFT Precoded Filter Bank Scheme With Low Complexity Equalizers in Time-Frequency Domain

open access: yesIEEE Access, 2023
Recently, the two-dimensional (2D) fast Fourier transform (2D-FFT) filter bank (FB) technique was proposed as an alternative to new wireless communication technologies covering several application scenarios.

Full and equal equality [PDF]

open access: yesTizard Learning Disability Review, 2018
Purpose This commentary takes the article, “Participation of adults with learning disabilities in the 2015 United Kingdom General Election”, as a jumping-off point for considering a tension between the aim of full and equal equality for all people with disabilities as set out in the Convention on the Rights of Persons with Disabilities and more ...

Learning Rate Updating Methods Applied to Adaptive Fuzzy Equalizers for Broadband Power Line Communications

open access: yesEURASIP Journal on Advances in Signal Processing, 2004
This paper introduces adaptive fuzzy equalizers with variable step size for broadband power line (PL) communications. Based on delta-bar-delta and local Lipschitz estimation updating rules, feedforward, and decision feedback approaches, we propose ...

Deep Neural Network Equalization for Optical Short Reach Communication

open access: yesApplied Sciences, 2019
Nonlinear distortion has always been a challenge for optical communication due to the nonlinear transfer characteristics of the fiber itself. The next frontier for optical communication is a second type of nonlinearities, which results from optical and ...
