Fig. 8From: A construction of the high-rate regular quasi-cyclic LDPC codesa The bit error rate and b frame error rate performance of two LDPC codes in example 3. In these figures, the circle solid line represents the performance of the regular quasi-cyclic (7280,6371) LDPC code with coding rate 7/8 generated by the procedure from (4) to (38). The box dotted line corresponds to the performance of the (8176,7156) QC-LDPC code constructed by the scheme of [16]. These 2 LDPC codes are both decoded with 50 iterations of the SPABack to article page
