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

Multithreshold decoder (MTD) is the simplest type of majority decoder that decodes self-orthogonal codes. Low computational complexity and simple decoding hardware implementation of multithreshold decoders allow using them in high speed communication systems and data storage systems that require decoding information at speeds above 1 Gbit/s. A high-speed software binary multithreshold decoder using a modern computing power of the graphics processing unit (GPU) is considered. Such software implementation of MTD helps to decode several hundred blocks received from the channel completely parallel and independent from each other. It is shown that the speed of software MTD based on GPU GTX 970 can reach 350 Mbit/s.
