Abstract :
This paper presents an improved permeable layer mechanism useful for highly robust packetized multimedia transmission. MAP estimation-based packet header recovery at various protocol layers is the cornerstone of the proposed solution. This header-correction technique exploits the available intra-layer and inter-layer header correlation to define a reduced set of header configurations. The best candidate is then selected in the pre-defined set through a soft decoding based on CRC redundancy. To improve the decoding performance, we also generalize the principle of UDP-Lite and propose a robust MAC layer, called MAC-Lite. Simulation results for WiFi transmission over AWGN channels assess a substantial (12 dB) link budget improvement.
