University of Washington researchers have demonstrated for the first time that devices that run on almost zero power can transmit data across distances of up to 2.8 kilometers — breaking a long-held b...
University of Washington researchers have shown that Google’s new tool that uses machine learning to automatically analyze and label video content can be deceived by inserting a photograph periodicall...
University of Washington researchers have shown that Google’s new machine learning-based system to identify toxic comments in online discussion forums can be bypassed by simply misspelling or adding u...
Technology companies routinely buildsprawling data centers to store all the baby pictures, financial transactions, funny cat videos and email messages its users hoard.But a new technique develope...
The upside of Wi-Fi is that it’s everywhere – invisibly connecting laptops to printers, allowing smartphones to make calls or stream movies without cell service, and letting online gamers battle it ou...
Heterostructures formed by different three-dimensional semiconductors form the foundation for modern electronic and photonic devices. Now, University of Washington scientists have successfully combine...
Since the first laser was invented in 1960, they’ve almost always given off heat — either as a useful tool, a byproduct or a fictional way to vanquish intergalactic enemies.But those concentrated beam...
A University of Wyoming professor has made a discovery that answers a nearly 100-year-old question about water movement, with implications for agriculture, hydrology, climate science and other fields....
To make cars as safe as possible, we crash them into walls to pinpoint weaknesses and better protect people who use them.That’s the idea behind aseries of experimentsconducted by a University of Washi...

设计了一种基于UW(Unique Word)帧结构的单载波频域均衡(SC-FDE)水声通信系统框架,论述了系统的基本原理。为解决帧同步过程中出现由水声多径引起的相关峰峰值分裂现象,提出一种基于UW序列的相关同步算法,使系统的同步精度显著提高。同时给出了基于UW序列的多普勒频移的估计和校正、信道估计和频域均衡算法。最后对系统的性能进行了分析。结果表明:采用相关同步算法的基于UW帧结构的单载波频域均衡...
