Abstract
In this paper, we propose the novel additional data transmission technology for DQPSK-OFDM based T-DMB system using watermarking technique. The proposed algorithms which is possible that it can transmit data in indoor or shadow region and improve transmission efficiency. We certified availability of our proposed technology by using various simulation. The results of the paper can be applied to wireless multimedia digital broadcasting systems.
