摘要: A class of geometrically structured quasi-cyclic low-density paritycheck codes with a cylinder structure graph and girth 12 is considered. The parity-check matrix such code consists blocks zeros circulant permutation matrices. convolutional assigned to these codes. form generator obtained by elementary row column operations. It shown that the free distance equal minimum their bock counterparts.
