On Construction of Moderate-Length LDPC Codes over Correlated Erasure Channels
The design of moderate-length erasure correcting low-density parity-check (LDPC) codes over correlated erasure channels is considered. Although the asymptotic LDPC code design rema...

Source fidelity over fading channels: performance of erasure and scalable codes
We consider the transmission of a Gaussian source through a block fading channel. Assuming each block is decoded independently, the received distortion depends on the tradeoff betw...

Causal Compensation for Erasures in Frame Representations
In a variety of signal processing and communications contexts, erasures occur inadvertently or can be intentionally introduced as part of a data reduction strategy. This paper disc...

Insight into redundancy schemes in DHTs
In order to provide high data availability in peer-to-peer (P2P) DHTs, proper data redundancy schemes are required. This paper compares two popular schemes: replication and erasure...

The Information Lost in Erasures
Abstract--We consider sources and channels with memory observed through erasure channels. In particular, we examine the impact of sporadic erasures on the fundamental limits of los...

Universal decoding with an erasure option
Motivated by applications of rateless coding, decision feedback, and automatic repeat request (ARQ), we study the problem of universal decoding for unknown channels in the presence...

Erasure and Polymorphism in Pure Type Systems
We introduce Erasure Pure Type Systems, an extension to Pure Type Systems with an erasure semantics centered around a type constructor indicating parametric polymorphism. The eras...

Just Forget It - The Semantics and Enforcement of Information Erasure
Abstract. There are many settings in which sensitive information is made available to a system or organisation for a specific purpose, on the understanding that it will be erased o...

End-to-End Enforcement of Erasure and Declassification
Declassification occurs when the confidentiality of information is weakened; erasure occurs when the confidentiality of information is strengthened, perhaps to the point of comple...
