%X A new method for geometric construction of QC-LDPC is proposed. The parity-check matrix constructed through this method has a girth more than eight,which promises good performance. Since the parity-check matrix is composed of cyclic sub-matrices,the hardware encoder is simple. Simulations show that this type of LDPC codes has remarkable performance with low encoding complexity.
