Channel Coding and Source Coding With Increased Partial Side Information
Entropy, 2017 Let ( S 1 , i , S 2 , i ) ∼ i . i . d p ( s 1 , s 2 ) , i = 1 , 2 , ⋯ be a memoryless, correlated partial side information sequence. In this work, we study channel coding and source coding problems where the partial side

Entropy-Constrained Scalar Quantization with a Lossy-Compressed Bit
Entropy, 2016 We consider the compression of a continuous real-valued source X using scalar quantizers and average squared error distortion D. Using lossless compression of the quantizer’s output, Gish and Pierce showed that uniform quantizing yields the smallest ...

An End-to-End Scheme for Learning Over Compressed Data Transmitted Through a Noisy Channel
IEEE Access, 2023 Within the emerging area of goal-oriented communications, this paper introduces a novel end-to-end transmission scheme dedicated to learning over a noisy channel, under the constraint that no prior training dataset is available.

Secure source coding with a helper [PDF]
2009 47th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2009 We consider a secure source coding problem with a rate-limited helper. In particular, Alice observes an independent and identically distributed (i.i.d.) source X and wishes to transmit this source losslessly to Bob over a rate-limited link. A helper (Helen), observes an i.i.d. correlated source Y and can transmit information to Bob over a separate rate-

Normalization of Java Source Codes [PDF]
, 2019 Security issues can be leveraged when input parameters are not checked. These missing checks can lead an application to an unexpected state where an attacker can get access to assets. The tool Chucky-ng aims at detecting such missing checks in source code. Such source codes are the only input required for Chuck-yJava.

On locally decodable source coding [PDF]
2015 IEEE International Conference on Communications (ICC), 2015 Locally decodable channel codes form a special class of error-correcting codes with the property that the decoder is able to reconstruct any bit of the input message from querying only a few bits of a noisy codeword. It is well known that such codes require significantly more redundancy (in particular have vanishing rate) compared to their non-local ...

On the Asymptotic Optimality of a Low-Complexity Coding Strategy for WSS, MA, and AR Vector Sources
Entropy, 2020 In this paper, we study the asymptotic optimality of a low-complexity coding strategy for Gaussian vector sources. Specifically, we study the convergence speed of the rate of such a coding strategy when it is used to encode the most relevant vector ...
