On the performance of LDPC-RS product codes for mobile DTV

This paper proposes an LDPC-RS product codes for the future terrestrial DTV system, which has to face an increasing demand of high spectrum efficiency and reliability. Particularly, we develop an adaptive decoding algorithm that can switch dynamically according to the SNR of received signals. Our algorithm consists of two key approaches, namely error estimation (EE) and soft value modification (SVM). Simulation results show that our proposed LDPC-RS product codes can correct mixed types of errors (random/burst) and achieve lower BER with less computational complexity.
