LDPC FEC Code Extension for Unequal Error Protection in DVB-T2 System: Design and Evaluation

Figure 4

Performance of LDPC codes over AWGN channel (a) and TU6 channel (b). The 3/5 and 1/2 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 with code rate 3/5 extended to the code rate 1/3 using the proposed method.
