Construction of protograph-based LDPC codes with chordless short cycles

Controlling small size trapping sets and short cycles can result in LDPC codes with large minimum distance \(d_{\min}\). We prove that short cycles with a chord are the root of several trapping sets and eliminating these cycles increases \(d_{\min}\). We show that the lower bounds on \(d_{\min}\) of...
