In network delivery of compressed video, packets may be lost if the channel is unreliable. Such losses tend to occur in burst. In this paper, we develop an error resilient video encoding approach to help error concealment at the decoder. We introduce a new block shuffling scheme to isolate erroneous blocks caused by packet losses. And we apply data hiding to add additional protection for motion...
In this paper, we investigate the transmission of H.263 video sequences over wireless networks with error recovery provided by a twostep adaptive hybrid ARQ scheme using RS codes. Each video frame is divided into data packets for transmission. For each packet transmission, by using a simple table-driven approach, the best RS code is selected from a given set of codes to minimize the transmissio...
In this paper, we improve the performance of the TiR-UWB communication systems with the non-ideal estimation of the channel. Time Reversal (TiR) technique is an effective and simple method for data transmission in extremely multipath indoor UWB channels that mitigates the complexity of receiver by its own time focusing feature. Although, TiR method has the suitable performance, but it is sensit...
