Prioritized Distributed Video Delivery with Randomized Network Coding

Pascal Frossard, Nikolaos Thomos, Jakov Cakareski

We address the problem of prioritized video streaming over lossy overlay networks. We propose to exploit network path diversity via a novel Randomized Network Coding (RNC) approach that provides unequal error protection (UEP) to the packets conveying the v ...

A 5.35 mm2 10GBASE-T Ethernet LDPC Decoder Chip in 90 nm CMOS

Andreas Peter Burg, Paolo Ienne, Yusuf Leblebici, Alessandro Cevrero

A partially parallel low density parity check (LDPC) decoder compliant with the IEEE 802.3an standard for 10GBASE-T Ethernet is presented. The design is optimized for minimum silicon area and is based on the layered offset-min-sum algorithm which speeds up ...

Exploiting the Path Propagation Time in Multipath Transmission with FEC

We consider a transmission of a delay-sensitive data stream from a single source to a single destination. The reliability of this transmission may suffer from bursty packet losses - the predominant type of failures in today's Internet. An effective and wel ...

On the Performance of Random Linear Network Coding in Relay Networks

Ramin Khalili

We compare the reliability performance gain of Random Linear Network Coding (RLNC) with Automatic Repeat Request (ARQ) for a wireless relay network taking into account overhead and complexity of feedback mechanism as well as overhead due to encoding vector ...

Optimisation of a Thick-Film 10...400 N Force Sensor

Peter Ryser, Thomas Maeder, Giancarlo Corradini, Niklaus Johner, Gregory Affolter

Abstract: The ring-on-ring bending principle allows the fabrication of simple, low-cost thick-film piezoresistive sensors for compressive forces in the 10 to 400 N range. However some imperfections are encountered in its basic embodiment, such as relativel ...

An automatic parameter extraction method for the 7x50m Stroke Efficiency Test

Jürg Markus Germann

We developed an automatic method to extract the parameters of the 7 x 50m Stroke Eficiency Test for swimming based on a wrist worn acceleration sensor device. In the wrist acceleration signal we detect characteristic swim events such as wall push-offs, wal ...

Diversity-Multiplexing-Delay Tradeoff in Half-Duplex ARQ Relay Channels

Sanket Dusad

In this paper, we present an efficient protocol for the delay-limited fading ARQ single relay half duplex channel. The source is using an ARQ retransmission protocol to send data to the relay and the destination. When the relay is able to decode, both the ...

On feedback for network coding

Christina Fragouli

In this paper we examine possible ways that feedback can be used, in the context of systems with network coding capabilities. We illustrate, through a number of simple examples, that use of feedback can be employed for parameter adaptation to satisfy QoS r ...

Using zero-rate feedback on binary additive channels with individual noise sequences

Michael Christoph Gastpar

Recently, Shayevitz and Feder introduced an individual sequence formulation of channel coding under model uncertainty and an elegant coding strategy that adapts Horstein's scheme to this setting to achieve the empirical capacity of the channel. Their schem ...
