| Abstract: | A new method for constructing Quasi-Cyclic (QC) Low-Density Parity-Check (LDPC) codes based on Euclidean Geometry (EG) is
presented. The proposed method results in a class of QC-LDPC codes with girth of at least 6 and the designed codes perform
very close to the Shannon limit with iterative decoding. Simulations show that the designed QC-LDPC codes have almost the
same performance with the existing EG-LDPC codes. |
