Summary:
In this paper, we described DVB-SSP system for mobility. The DVB-SSP for mobility system used cross layer scheme which is consist of e-RS(erasure Reed-Solomon), virtual interleaver and LDPC. Erasure data for e-RS decoding is detected by CRC check in conventional DVB-SSP system. However, this paper proposed erasure data detecting method by LLR value of LDPC. It is called LLR method. Through the simulation results, we know that the performance of LLR method is better than conventional CRC method as 0.2dB.
