Pilotless Frame Synchronization for LDPC-Coded Transmission Systems
Abstract--We present a pilotless frame synchronization approach that exploits feedback from a low-density parity-check (LDPC) code decoder. The synchronizer is based on syndrome ch...

Single-iteration full-search fractional motion estimation for quad full HD H.264/AVC encoding
Fractional motion estimation (FME) is widely used in video compression standards. In H.264/AVC, the precision of motion vector is down to quarter pixels to improve the coding effi...
