Local recovery with error tolerance for locally recoverable codes
Genki Oiwa, Hideki Yagi (UEC) IT2020-47
Abstract (in Japanese) (See Japanese page) 
(in English) Locally recoverable codes (LRC codes) can restore the lost codeword symbol by referring to surrounding codeword symbols. The local recovery of LRC codes is usually discussed under the assumption that there are no errors. However, it is desirable that the LRC codes can correctly estimate the erased codeword symbol even in the presence of errors. Also, it is not realistic to assume that there are no errors.
In this paper, we propose a local recovery method in the situations where errors and erasures occur at the same time. As a result, more practical local recovery can be realized.
