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
plexity 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.
Key words: fountain codes; GF(m) random linear fountain codes; multi-interface wireless
