LDPC FEC Code Extension for Unequal Error Protection in DVB-T2 System: Design and Evaluation
Figure 6
Performance of LDPC codes over AWGN channel (a) and TU6 channel (b). The 2/3, 3/4, and 4/5 curves show performance of the native DVB-T2 LDPC codes with corresponding code rates. The curve shows performance of the native DVB-T2 LDPC code with the code rate 4/5 extended to code rate 2/3 using the proposed method.
