Abstract:

A locally recoverable code is a code over afinite 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). Thus, it is a challenging problem to construct q-ary locally recoverable codes with distance d > 5 and length approaching the upper bound. In this talk, we present an explicit construction of q-ary locally recoverable codes of distance d = 5 and 6.
