摘要： 通过对多种多媒体传输标准纠错编码技术的研究,结合跳频WLAN信道特性,提出了一种应用于WLAN的移动多媒体传输LDPC+RS级联纠错码方案。仿真实验表明,与用于数字广播网移动多媒体传输的DVB-H标准纠错码方案相比,该方案的纠错性能有明显的提高,在基于跳频WLAN的移动多媒体传输系统中应用具有一定的优势。
Abstract: In this paper,we have studied the error correction code technology of multimedia transmit standard. Based on the characteristics of the frequency-hop WLAN channel,a novel LDPC+RS concatenated coding scheme for mobile multimedia transmit based on frequency-hop WLAN is proposed.Simulation results show that this proposed scheme provides good performance compared with DVB-H standard.This proposed scheme is more suitable for mobile multimedia transmission system based on frequency-hop WLAN.
