报告简介:

Quasi-cyclic codes generalize cyclic codes. They have applications in distributed storage and modern communication systems because they admit efficient encoding and decoding algorithms. In this paper, we give a technique to construct quasi-cyclic codes using the Kronecker product. Using parity-check matrices of cyclic codes and a sequence of nested codes, we design a parity-check matrix of a quasi-cyclic code. This construction targets a designed minimum distance. It is easier to implement than the method derived from the spectral theory of quasi-cyclic codes. Using this construction, we present several infinite families of quasi-cyclic codes with good parameters. In particular, we obtain seven infinite families of distance-optimal quasi-cyclic codes with respect to the sphere packing bound.
