Abstract:	This article presents a simple, less computational complexity method for constructing exponent matrix ( ) 3, K having girth at least 8 of quasicyclic low-density parity-check (QC-LDPC) codes based on subtraction method. The construction of code deals with the generation of exponent matrix by three formulas. This method is flexible for any block-column length K . The simulations are shown in comparison with some existing appreciable work. The codes with girth 8 are constructed with circulant permutation matrix (CPM) size P max a ≥ {a a 2, 2, 2, rr k , , . 1.
