摘要: A locally recoverable code is a code over a finite alphabet such that the value of any single coordinate of a codeword can be recovered from the values of a small subset of other coordinates. Such codes have recently attracted great attention as efficient solutions for distributed storage systems. It was shown by Guruswami et al. that the length n of a q-ary linear locally recoverable code with distance d > 5 is upper bounded by O(dq^3). In this talk, we present an explicit construction of q-ary locally recoverable codes of small distances.
