Abstract :
This paper describes a new error correction scheme for flexible and robust high-throughput real time video transmission systems able to cope with difficult high mobility channels. The scheme is based on combining OFDM transmission with turbo coding and deep time interleaving. Simulations of different channel models and field test has shown that the provided solution provides relevant improvement versus DVB-T based solutions.
