Construction and Performance Analysis of BIBD-QC-LDPC Codes for Correcting Erasure-Bursts

This paper presents a novel approach for constructing structured regular QC-LDPC codes based on a special type of combinatorial designs,known as the balanced incomplete block design (BIBD).The code design approach based on the technology of block cyclic shift and dispertion (BCSD) for correcting erasure-bursts over the binary bursts erasure channel (BBEC). Furthermore, the Tanner graph of the constructed codes is free of 4cycles, hence the BCSD-QC-LDPC codes have girth at least 6. The simulation results show that the BCSD-QC-LDPC codes perform well over the BBEC channel with iterative message-passing decoding.
