Experimental characterization of a 400 Gbit/s orbital angular momentum multiplexed free-space optical link over 120 m [PDF]
, 2016 We experimentally demonstrate and characterize the performance of a 400-Gbit/s orbital angular momentum (OAM) multiplexed free-space optical link over 120- meters on the roof of a building.

On Learned Operator Correction in Inverse Problems [PDF]
arXiv, 2020 We discuss the possibility to learn a data-driven explicit model correction for inverse problems and whether such a model correction can be used within a variational framework to obtain regularised reconstructions. This paper discusses the conceptual difficulty to learn such a forward model correction and proceeds to present a possible solution as ...

Staircase Codes: FEC for 100 Gb/s OTN [PDF]
, 2012 Staircase codes, a new class of forward-error-correction (FEC) codes suitable for high-speed optical communications, are introduced. An ITU-T G.709-compatible staircase code with rate R=239/255 is proposed, and FPGA-based simulation results are presented, exhibiting a net coding gain (NCG) of 9.41 dB at an output error rate of 1E-15, an improvement of ...

Embedding Protection Inside H.264/AVC and SVC Streams
EURASIP Journal on Wireless Communications and Networking, 2010 A backward compatible error-protection mechanism embedded into the H.264 (AVC or SVC) syntax is described. It consists of the addition into the H.264 bitstream of supplementary network abstraction layer (NAL) units that contain forward error-correction (

Adaptable Forward Error Correction for Multimedia Data Streams [PDF]
, 1993 The error handling method in traditional communication protocols is error detection and retransmission. This method is inappropriate for distributed multimedia systems for two reasons: It introduces variable delay unacceptable for isochronous streams ...

Learning from your mistakes: The functional value of spontaneous error monitoring in aphasia
Frontiers in Psychology, 2014 Self-monitoring of errors in picture naming has been shown to correlate positively with aphasia treatment outcomes (Marshall et al., 1994). To explore potential explanations, we took advantage of aphasics’ item-level inconsistency in naming accuracy, e ...

SELECTIVE FORWARD ERROR CORRECTION WITH FULL DUPLEX FEEDBACK LOOP [PDF]
, 2020 Numerous techniques exist for detecting and correcting errors that are introduced during the transmission of information (e.g., a data frame) between two pieces of network equipment, including, for example, forward error correction (FEC), cyclic ...

Using Deep Cross Modal Hashing and Error Correcting Codes for Improving the Efficiency of Attribute Guided Facial Image Retrieval [PDF]
arXiv, 2019 With benefits of fast query speed and low storage cost, hashing-based image retrieval approaches have garnered considerable attention from the research community. In this paper, we propose a novel Error-Corrected Deep Cross Modal Hashing (CMH-ECC) method which uses a bitmap specifying the presence of certain facial attributes as an input query to ...
