Cross-Correlated FEC Scheme for Multimedia Streaming over Wireless LAN

The recent video standards like MPEG-4 are generally vulnerable to the packet loss because they achieve high compression ratios by complex calculation of preceding and succeeding frames. But, in the wireless channel, errors tend to occur in burst due to the intrinsic wireless link characteristics. Therefore, an efficient error control mechanism for multimedia streaming is necessary. In this paper, we propose a novel CC-FEC (Cross-correlated Forwarding Error Correction) scheme robust against burst error and suitable for multimedia streaming over the WLAN. The proposed scheme takes advantage of the interleaving and the multi-dimensional FEC schemes. We verify our scheme's superior performance than other FEC schemes through simulation.
