Abstract :
This contribution deals with the transmission of video packets over a wireless link subject to slow Rayleigh fading. In order to provide protection against transmission errors and video packet erasures, we apply forward error correction (FEC) both on the physical layer and the packet layer, which involves the transmission of parity bits and parity packets that enable to recover a number of bit errors and packet erasures. We present an expression for the diversity gain provided, in terms of the fading coherence time, the allowable latency, and the allowable transmission overhead.
