Cross-Layer Frame Synchronization for H.264 Video OverWIMAX

Date Added: Apr 2010

In the WIMAX (802.16e) standard several small Medium Access Control (MAC) packets may be aggregated to form a MAC burst, forwarded to the PHYsical (PHY) layer The burst transmission is a mechanism to allow multiple MAC Protocol Data Units (PDUs) belonging to the same video channel to be transmitted/received in an aggregated way, in order to enable power saving at the mobile station, by putting the transceiver in sleep mode during off-burst interval. As a consequence of it, at the receiver side individual packets should be isolated within a burst, i.e. frame synchronization should be performed.
