报告摘要:
This talk focuses on the bounds and constructions of binary linear LRCs. Particularly, two new upper bounds on the dimension of binary linear LRCs are presented. The first one is an explicit bound for binary linear LRCs with disjoint repair groups, which can be regarded as an extension of known explicit bounds for such LRCs to more general code parameters. The second one is based on an optimization problem, and can be applied to any binary linear LRC. Then we give a new construction of binary linear LRCs, and prove their optimality with respect to the simplified bound.
