... propose cooperative protocols for video transmission to better utilize system resources for performance improvement. Moreover, because of the broad- cast nature of the phase 1 in cooperative transmission, ... video transmission with side information, we have obtained up to 4 dB gain over the amplify-and-forward or decode-and-forward protocols. For the multiuser case, w...
