Multimedia Communication Over Ofdm Mobile Wireless Networks: A Cross-Layer Diversity Approach |
Abstract | ||
---|---|---|
Diversity can be used to combat multipath fading and improve the performance of mobile wireless multimedia communication systems. In this work, by considering transmission of an embedded bitstream over a slow varying Rayleigh faded environment, we develop a cross-layer diversity technique which takes advantage of both multiple description source coding and frequency diversity techniques. More specifically, assuming a frequency-selective channel, we study the packet loss behavior of an OFDM system and construct multiple independent descriptions using an FEC-based strategy. We demonstrate the superior performance of this approach using the Set Partitioning in Hierarchical Trees (SPIHT) coder. |
