A Multi-Key Pirate Decoder Against Traitor Tracing Schemes
In this paper we introduce an architecture for a multi-key pirate decoder which employs decryption keys from multiple traitors. The decoder has built-in monitoring and self protect...

Feature-Rich Translation by Quasi-Synchronous Lattice Parsing
We present a machine translation framework that can incorporate arbitrary features of both input and output sentences. The core of the approach is a novel decoder based on lattice...

Improving Phrase-Based Translation with Prototypes of Short Phrases
We investigate methods of generating additional bilingual phrase pairs for a phrasebased decoder by translating short sequences of source text. Because our translation task is mor...

Distributed joint source-channel arithmetic coding
We deal with the problem of distributed source coding with decoder side information, when the decoder observes the source through a noisy channel. Existing approaches employ syndr...

A Split-Decoding Message Passing Algorithm for Low Density Parity Check Decoders
A Split decoding algorithm is proposed which divides each row of the parity check matrix into two or multiple nearly-independent simplified partitions. The proposed method signific...

Two Methods for Decreasing the Computational Complexity of the MIMO ML Decoder
We propose use of QR decomposition with sort and Dijkstra's algorithm for decreasing the computational complexity of the sphere decoder that is used for ML detection of signa...

Unified Convolutional/Turbo Decoder Design Using Tile-Based Timing Analysis of VA/MAP Kernel
To satisfy the advanced forward-error-correction (FEC) standards, in which the Convolutional code and Turbo code may co-exit, a prototype design of a unified Convolutional/Turbo de...

Variations on Information Embedding in Multiple Access and Broadcast Channels
Information embedding (IE) is the transmission of information within a host signal subject to a distortion constraint. There are two types of embedding methods, namely irreversibl...
