| Abstract: | GF（m）random linear fountain codes and its on-the-fly Gaussian Elimination （OFG）decode algorithm are discussed,its decoding overhead and decoding complexity are analyzed,and a parameter selection scheme is proposed.To demonstrate the effi-ciency of the proposed scheme,several tests are run on the multi-interface wireless multimedia transmission system to which the scheme is applied.The test results show that both the transmission speed and reliability of the system are near optimal. |
