Abstract
This paper presents an enhanced permeable layer mechanism useful for reliable packetized multimedia transmission. Packet header recovery at various protocol layers using MAP estimation is the cornerstone of the proposed solution. The available intra-layer and inter-layer header correlation is used to define a reduced set of header configurations for further processing. The best candidate is then obtained through soft decoding based on CRC redundancy. Simulation results for a WiFi transmission scheme using DBPSK modulated signals over an AWGN channel show a substantial (4 to 12 dB) link budget improvement. A sub-optimal and hardware realizable version of the proposed algorithm is also presented.
