A Novel 3-D Interleaving Method for Video Transmission over OFDM in Mobile Wireless Channels
Reliable video transmission over mobile wireless channels faces many challenges due to the timevarying multi-path fading. In this paper, a novel 3-D interleaving method, called Spatial Frequency Temporal Interleaving (SFTI), is proposed for video transmission over OFDM systems in this kind of channels. SFTI means the video data will be interleaved both at bit level in spatial domain, which can disperse the error bits to make the channel coding more effective, and slice level in Frequency and temporal domain, which can alleviate the impact of burst bit errors by limiting the bit errors in some area of the picture, thus the error concealment is facilitated. Simulation results show that the proposed method can improve the quality of the reconstructed video.
