Correcting Confusion Matrices for Phone Recognizers

Modern speech recognition has many ways of quantifying the misrecognitions a speech recognizer makes. The errors in modern speech recognition makes extensive use of the Levenshtein algorithm to find the distance between the labeled target and the recognize ...

Robust Transmission of H.264/AVC Streams Using Adaptive Group Slicing and Unequal Error Protection

Nikolaos Thomos

We present a novel scheme for the transmission of H.264/AVC video streams over lossy packet networks. The proposed scheme exploits the error-resilient features of H.264/AVC codec and employs Reed-Solomon codes to protect effectively the streams. A novel te ...

Methods and apparatus employing FEC codes with permanent inactivation of symbols for encoding and decoding processes

Mohammad Amin Shokrollahi

A method of encoding data for transmission from a source to a destination over a communications channel is provided. A plurality of encoded symbols are generated from a set of input symbols including source symbols and redundant symbols, wherein the input ...

Systematic Errors in Computed Alkane Energies Using B3LYP and Other Popular DFT Functionals

Matthew Wodrich

Energies computed by B3LYP and other popular DFT functionals are flawed by systematic errors, which can become considerable for larger mols. These errors, predominately due to inadequacies in assessing longer-range nonbonded attractive effects (dispersion) ...

Systematic encoding and decoding of chain reaction codes

Mohammad Amin Shokrollahi

A method of encoding data into a chain reaction code includes generating a set of input symbols from input data. Subsequently, one or more non-systematic output symbols is generated from the set of input symbols, each of the one or more non-systematic outp ...

On the capacity of erasure relay channel: Multi-relay case

Ramin Khalili

We consider here a single sender-destination multirelay channel. The links connecting the nodes are supposed to be erasure where symbols are received correctly without any error, or lost. We consider that the nodes are not able to use any interference canc ...

On the capacity of multiple input erasure relay channels: The Non-degraded case

Ramin Khalili

We consider in this paper a network that consists of two senders and two receivers. We further assume that each sender could act as a relay for other communications. All channels connecting these nodes are supposed to be erasure channels where symbols are ...

Asymptotic and finite-length analysis of low-density parity-check codes

Changyan Di

This thesis addresses the topic of Low-Density Parity-Check (LDPC) code analysis, both asymptotically and for finite block lengths. Since in general it is a difficult problem to analyze individual code instances, ensemble averages are studied by following ...
