Blind equalization of DS-CDMA and MC-CDMA modulations in time-variant frequency selective channels [PDF]

open access: yes, 1999
The paper addresses the blind equalization problem of spread spectrum modulations in the presence of fast time-variant frequency-selective channels. The basic assumption of the paper is that the channel response exhibits fast changes.

Experimental Demonstration of 40-Gb/s I-SC-FDM With 10G-Class Optics and Low-Complexity DSP for Next-Generation PON

open access: yesIEEE Photonics Journal, 2018
Low cost and low energy consumption are two important issues for the upgrade of next-generation passive optical network (PON). In this paper, we experimentally demonstrated a 40-Gb/s PON downstream transmission employing interleaved single carrier ...

Enhancing Equality

open access: yesThe Journal of Medicine and Philosophy: A Forum for Bioethics and Philosophy of Medicine, 2019
The range of opportunities people enjoy in life largely depends on social, biological, and genetic factors for which individuals are not responsible. Philosophical debates about equality of opportunities have focussed mainly on addressing social determinants of inequalities.

‘Equal play, equal pay’: moral grounds for equal pay in football [PDF]

open access: yesJournal of the Philosophy of Sport, 2019
In this paper, we investigate three different ways of defending the claim that national football associations ought to pay their men's and women's football teams the same amount. First, we consider an argument that appeals to the principle of equal pay for equal work.
