摘要

本文提出了一种增强的可渗透层机制，用于可靠的分组多媒体传输。使用MAP估计在各个协议层恢复包头是所提出的解决方案的基础。可用的层内和层间报头相关性用于定义一组简化的报头配置，以供进一步处理。然后通过基于CRC冗余的软解码获得最佳候选。在AWGN信道上使用DBPSK调制信号的WiFi传输方案的仿真结果显示，链路预算大幅改善(4至12 dB)。本文还提出了该算法的次优和硬件可实现版本。

Robust header recovery based enhanced permeable protocol layer mechanism

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.
