Clustering For Designing Error Correcting Codes
(Indian Institute of Science, 2005-02-11)In this thesis we address the problem of designing codes for specific applications. To do so we make use of the relationship between clusters and codes. Designing a block code over any finite dimensional space may be thought ... -
Coded Caching in Multi-access Networks
Caching is a promising technique that can reduce the amount of data transmitted over latency-prone links, effectively trading affordable memory for expensive bandwidth resources. The frequently demanded content is stored ... -
Codes closed under arbitrary abelian group of permutations
Discrete Fourier Transform (DFT) is a widely used tool in the field of electrical engineering. In the name of Mattson-Solomon polynomials, DFT was used in the context of linear cyclic codes in the early days of coding ... -
Codes for distributed storage, private information retrieval and low-latency streaming
This thesis presents results on error correcting codes for settings such as: (a) distributed storage, (b) private information retrieval, and (c) low-latency streaming. It also presents two new decoding algorithms for Polar ... -
Codes over galois rings closed under certain monomials
The use of error-control coding in information transmission systems and data storage systems is increasing rapidly. The primary aim of coding theorists has been to find “good codes” with “reasonably simple” decoding methods. ... -
