This letter presents an improved decoding algorithm for distributed video coding (DVC) for enhanced performance over error prone wireless channels with multipath fading. The effects of the channel errors on both Wyner-Ziv and key frame bit streams are considered and novel noise models are proposed together with the associated modifications to the decoding algorithm. Simulations are performed using a W-CDMA wireless channel and the results are analyzed to determine the effect of each individual modification. State-of-the-art H.264/AVC is also considered under similar conditions for the comparison. The simulation results show that the proposed modifications provide a significant improvement in the DVC codec performance under unfavorable channel conditions. |
