Design of Nonbinary LDPC Cycle Codes with Large Girth from Circulants and Finite Fields
Figure 5
The error performances of the constructed (304,152) QC-LDPC cycle code over GF (256) and the comparable (2432,1216) LDPC code over GF (2) constructed based on the progressive edge-growth (PEG) algorithm in [46]. The transmissions on the BPSK modulated AWGN channel are assumed.
