On a Family of Circulant Matrices for Quasi-Cyclic Low-Density Generator Matrix Codes
We present a new class of sparse and easily invertible circulant matrices that can have a sparse inverse though not being permutation matrices. Their study is useful in the design of quasi-cyclic low-density generator matrix codes that are able to join the inner structure of quasi-cyclic codes with sparse generator …
