Optimal codes correcting localized deletions
WebWe present novel explicit codes that are efficiently encodable and decodable and can correct up to $k$ localized deletions. Furthermore, these codes have $\log … Webcodes for correcting deletions that are localized within a certain part of the codeword that is unknown a priori. The model that we study is when wdeletions occur in a window of size at most wbits. These deletions are not necessarily consecutive, but are restricted to a window of size w. The localized deletions model is a generalization of the ...

We present novel explicit codes that are efficiently encodable and … WebThe problem was first studied for binary sequences by Levenshtein, who presented a construction with optimal redundancy. We propose a non-binary code correcting a burst of at most 2 deletions for q-ary alphabets with redundancy log n+O (log q log log n) bits, for even q. Further, we construct codes with lower redundancy to correct a burst of ...
WebJun 26, 2024 · Abstract: In this paper, we present an efficiently encodable and decodable code construction that is capable of correcting a burst of deletions of length at most k. The redundancy of this code is log n + k(k + 1)/2 log log n + c k for some constant c k that only depends on k and thus is scaling-optimal. The code can be split into two main … WebMay 5, 2024 · This work considers the problem of constructing codes that can correct deletions that are localized within a certain part of the codeword that is unknown a priori …
WebError-correcting codes. We will study the design of error-correcting codes over sets that are suitable for data storage in DNA. Errors within this model are losses of sequences and point errors inside the sequences, such as insertions, deletions, and substitutions.
