Constructing short-length QC-LDPC codes without girth-4 and girth-6 cycles
When designing short-length QC-LDPC codes, special attention must be paid to eliminate girth-4 and girth-6 cycle structures. This approach significantly improves codeword reliability and error correction capability. By excluding these specific cycle patterns through careful base matrix design and circulant permutation matrix selection, we can develop more efficient encoding schemes that meet diverse application requirements. Implementation typically involves algebraic construction methods or computer-aided search algorithms to verify cycle properties in the Tanner graph representation.
