From: A construction of the high-rate regular quasi-cyclic LDPC codes
a The bit error rate and b frame error rate performances of three LDPC codes in example 2. In these figures, the circle solid line represents the performance of the regular quasi-cyclic (6930,6301) LDPC code with coding rate 10/11 generated by the procedure from (4) to (38). The box and diamond dotted lines separately correspond to the (4095,3729) and (16383,14923) QC-LDPC codes which are constructed from the procedure of [16]. These 3 LDPC codes are all decoded with 50 iterations of the SPA
