Research on Applying Fountain Codes to Multi-interface Wireless Multimedia Transmission
Abstract:Applying fountain codes to multi-interface wireless multimedia transmission can increase both the speed and reliability of the transmission. In this paper, GF(m) random linear fountain codes and its OFG decode algorithm was discussed, and its decoding overhead and decodingcomplexity was analyzed, and a parameter selection scheme was proposed. To demonstrate the efficiency of the proposed scheme, serveral tests was run on the multi-interface wireless multimedia transmission system which the scheme is applied to, the results of these tests show that both the speed and reliability of the transmission of the system are near optimal.
