A Programmable Optical Network Testbed in Support of C-RAN: A Reliability Study
With both mobile network services and related data traffic volume on the rise, reliability of the radio access network is of the essence. A number of radio functional splits are defined by 3GPP to offer increased flexibility ... -
A Speech Processing Strategy Based on Sinusoidal Speech Model for Cochlear Implant Users
In sinusoidal modeling (SM), speech signal, which is pseudo-periodic in structure, can be approximated by sinusoids and noise without losing significant speech information. A speech processing strategy based on this ... -
Ab Initio Study of the Electronic Properties and Thermodynamic Stability of Supported and Functionalized Two-Dimensional Sn Films
Using density-functional theory (DFT), we study the growth of pristine and functionalized tin monolayers (Sn-MLs) on three different substrates, CdTe, InSb, and Si(111), and the impact these substrates have on the topological ... -
Accelerating Chemical Exchange Saturation Transfer MRI with Parallel Blind Compressed Sensing
Purpose: Chemical exchange saturation transfer is a novel and promising MRI contrast method, but it can be time-consuming. Common parallel imaging methods, like SENSE, can lead to reduced quality of CEST. Here, parallel ... -
