Abstract Digital fountain is a packet oriented forward error correction technology for channels with erasures, which has obvious efficiency advantage in broadcast. In the paper, LDPC code is put into practice in digital fountain encoding, and a fast decoding algorithm is presented. The simulation show that the digital fountain scheme base on LDPC code has better error correcting performance and can be implemented with very low complexity to encode and decode.
