| 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. |
