Low density parity check codes are a popular class of linear block codes for forward error correction in communication channels. Recent years have seen a lot of work towards the hardware-oriented constructions for LDPC codes which have comparable error-correcting performance to random construction codes. This paper proposes a novel method called Iterative-filled (IF) to construct LDPC codes and a new kind of LDPC codes named IF-LDPC codes. Based on the properties of the method proved in this paper, we present a design of regular and quasi-regular IF-LDPC encoders which have linear encoding complexity, simple construction, low memory requirement and are suitable for partly parallel decoding. These advantages make them easy to hardware implementation. The IF-LDPC codes exhibit good performance in computer simulations and some even better than MacKay codes.
