Fundamental Limits on Data Acquisition: Trade-offs between Sample Complexity and Query Difficulty
, 2018 We consider query-based data acquisition and the corresponding information recovery problem, where the goal is to recover $k$ binary variables (information bits) from parity measurements of those variables.

Near-Capacity Adaptive Analog Fountain Codes for Wireless Channels
, 2013 In this paper, we propose a capacity-approaching analog fountain code (AFC) for wireless channels. In AFC, the number of generated coded symbols is potentially limitless.

Coding for Fast Content Download [PDF]
, 2012 We study the fundamental trade-off between storage and content download time. We show that the download time can be significantly reduced by dividing the content into chunks, encoding it to add redundancy and then distributing it across multiple disks ...

“Pitch the king”: Ben Fountain’s games
Transatlantica, 2013 In his stories and his novel, Ben Fountain uses games as an epistemological tool. Games allow him to subvert the cultural codes, his satire becoming a political critique of the nation and of US foreign policy, and to operate a fusion of the characters ...

Inactivation Decoding of LT and Raptor Codes: Analysis and Code Design [PDF]
, 2017 In this paper we analyze LT and Raptor codes under inactivation decoding. A first order analysis is introduced, which provides the expected number of inactivations for an LT code, as a function of the output distribution, the number of input symbols and ...

Design and Analysis of Systematic Batched Network Codes
Entropy, 2023 Systematic codes are of important practical interest for communications. Network coding, however, seems to conflict with systematic codes: although the source node can transmit message packets, network coding at the intermediate network nodes may ...

Fountain-code Aided File Transfer in Vehicular Delay Tolerant Networks
Advances in Electrical and Computer Engineering, 2013 We propose a mechanism for facilitating file transferring in Vehicular Delay Tolerant Networks. The proposed architecture includes using Fountain coding in the application layer, UDP in the transport layer and a proposed DTN routing algorithm in the ...
