Wyner-Ziv video coding with error-prone wireless fading channels

Abstract

This research work explains the new video coding technique known as Wyner-Ziv video coding and its transmission over fading wireless channels. We have modeled the Wyner-Ziv codec with wireless channel. Impairments of the wireless channel (both noise and fading) are considered in the improvement of the Wyner-Ziv decoder. The cross-layer structure is introduced in the Wyner-Ziv video coding technique. We have analyzed the channel noise and the correlation noise of video frames at the decoder side. Estimation of the correlation noise between the Wyner-Ziv frame and the side information is studied thoroughly and proposed the new estimation technique which is known as the bit based correlation noise estimation. Furthermore, the performance of a multiple input multiple output (MIMO) diversity scheme is investigated to overcome the channel fading effect in the reconstructed Wyner-Ziv video frame sequence.
