%X In this paper, based on (n,2,k) regular Low Density Parity-Check (LDPC) codes without short cycles, a geometry method for the construction of(n,3,k) regular LDPC codes with 8-girth is proposed,which is simple,intuitionistic and effective. Simulation results show that these codes achieve obviously better performance than randomly constructed regular LDPC codes over AWGN channals.
