Finite length analysis of LT codes

Mohammad Amin Shokrollahi

This paper provides an efficient method for analyzing the error probability of the belief propagation (BP) decoder applied to LT Codes. Each output symbol is generated independently by sampling from a distribution and adding the input symbols corresponding ...

Sampling methods for parametric non-bandlimited signals

Irena Maravic

Sampling theory has experienced a strong research revival over the past decade, which led to a generalization of Shannon's original theory and development of more advanced formulations with immediate relevance to signal processing and communications. For e ...

Sampling of communications systems with bandwidth expansion

Martin Vetterli, Andrea Ridolfi

Many communication systems are {\em bandwidth-expanding}: the transmitted signal occupies a bandwidth larger than the {\em symbol rate}. The sampling theorems of Kotelnikov, Shannon, Nyquist et al. shows that in order to represent a bandlimited signal, it ...

Reactive infiltration processing of aluminum-nickel intermetallic compounds

Andreas Mortensen

Aligned nickel wire bundles 4 to 5 cm in length and up to 2.5 cm in diameter are infiltrated by pure aluminum using gas-assisted infiltration, to produce samples having global compositions in the range of 40 to 76 at, pet nickel. As-reacted sample macrostr ...

Electrothermal atomic absorption spectrometric determination of lead and tin in slurries. optimization study

A comparative study of the efficiencies of W, Mg, Mg + Pd, Ir + Mg and Ir + W + PO43- as chem. modifiers for the thermal stabilization of Pb and Sn in slurries was performed. The Ir + Mg modifier contributes more than the others to minimizing matrix effect ...

Orientation of Rapid Thermally Annealed Lead-Zirconate-Titanate Thin-Films on (111) Pt Substrates

Nava Setter

The nucleation, growth, and orientation of lead zirconate titanate thin films prepared from organometallic precursor solutions by spin coating on (111) oriented platinum substrates and crystallized by rapid thermal annealing was investigated. The effects o ...
