Abstract

Orthogonal Frequency Division Multiplexing (OFDM) is a promising technique in broadband wireless communication systems. This paper presents a novel multi-reference scheme based on 3D interleaving for video coding and transmission over OFDM channel. Initially, a combining interleaving method in spatial, frequency and temporal domains, called SFTI, is proposed. With SFTI, different slices within one frame are transmitted in different sub-channels of OFDM, whose SNR can be estimated, and the transmission status of slices through these sub-channels are real-time feedback to the encoder. Based on the feedback information, a multi-reference scheme for video coding is proposed where the well-transmitted slices are selected as the reference picture of its consequent pictures in inter-frame coding to eliminate the impairment caused by error propagation in video transmission over wireless OFDM channels. Extensive experimental results have demonstrated the effectiveness of the proposed methods in error resilience.
