LDPC FEC Code Extension for Unequal Error Protection in DVB-T2 System: Design and Evaluation
Figure 5
Performance of LDPC codes over AWGN channel (a) and TU6 channel (b). The 1/2, 2/3, and 3/4 curves show performance of the native DVB-T2 LDPC codes with the corresponding code rates. The curve shows performance of the native DVB-T2 LDPC code with code rate 3/4 extended to the code rate 1/2 using the proposed method.
