Abstract
When arranging J cyclic permutation matrices I(p) with p rows and q columns (0≦j≦J−1, 0≦l≦L−1) in a row direction and also arranging L cyclic permutation matrices I(p) in a column direction so as to generate a regular quasi-cyclic matrix having uniform row and column weights, a quasi-cyclic matrix generating unitconfigures the regular quasi-cyclic matrix by combining cyclic permutation matrices I(p) in each of which matrix elements whose row number is r (0≦r≦p−1) and whose column number is (r+p) mod p are '1's, and other matrix elements are '0's in such a way that a plurality of cyclic permutation matrices I(p) arranged at, e.g., the 1st row differ from one another.
