英文摘要For locally repairable codes (LRCs), Cadambe and Nlazumdar derived the first field-dependent parameter hound, known as the C-M hound. However, the C-M hound depends on ( an undetermined parameter k(opt)((q)) (n, d). In this paper, a sphere packing approach is developed fir upper hounding the parameter k for [n, k, 61 linear LRCs with locality r. When restricted to the binary field, three upper bounds (i.e., Bound A, Bound B, and Bound C) are derived in an explicit form. More specifically, Bound A holds under the hypothesis that the local repair groups are disjoint and of equal size. Comparing with previous bounds obtained under the same hypothesis, Bound A either covers them as special cases or has an advantage due to its explicit form. Then, the hypothesis is removed in Bound B and Bound C. As the price for explicit thrm, Bound B specially holds for d >= 5 and Bound C for r = 2. Through specific comparisons, we show that Bound B and Bound C both tend to outperform the C-M hound, as n goes large. Moreover, a family of hinary linear LRCs with d >= 6 attaining Bound B are constructed and later extended to a wider range of parameters by a shortening technique. Lastly, most of the bounds and constructions are extended to q-ary LRCs.
