This paper uses linear error correction code(LECC) of the informatics encoding theoretics to solve the problems of slowness and low reliability on transmission of big data file.LECC algorithm partitions the data into blocks and encodes it redundantly,then the encoded packages are transmitted in the erasure channel(Internet for example).If enough encoded packages are received,the receiver can decode the original data,regardless of which package is lost.It saves the time for package acknowledging and retransmitting.In the experiment,the receiver can finish decoding as long as it gets 4 percent encoded packages more on average in LECC transmission,the cost of encoding,decoding and the increased packages transmitting is less than the ARQ error control′s in transmission of big data file.LECC algorithm improves the reliability of channel and the efficiency of data transmission.
