Abstract :
Campello, Modha and Rajagopalan (see Proc. Int. Conf. Communications (ICC), Helsinki, Finland, 2001) proposed a simple-to-implement heuristic, namely, bit-filling, for constructing high rate and high girth LDPC codes. In the present work, we extend bit-filling, and demonstrate that the extended algorithm produces better codes, that is, codes with higher rate/girth and good bit error rate performance. We demonstrate the positive effect of girth on bit error rate performance
