Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This paper discusses the impact of pulse shaping filter on the performance of orthogonal frequency division multiplexing (OFDM) based visible light communication (VLC) systems. Particularly, direct current biased optical OFDM (DCO-OFDM) with square-root-raised-cosine (SRRC) pulse shaping filters is investigated. The bit-error-rate (BER) performance of the system is evaluated for different excess bandwidth parameters (roll-off factors) and compared with the performance with rectangular pulse shaping filter through Monte Carlo simulations.
