摘要:
Fountain codes are erasure channels in superior performance of sparse matrix code. Files are transmitted into multiple small packets, each of which is either received without error or not received. Fountain codes are based on the packets communication. The decoder can start to transmit packets without any knowledge of which packets are received. In the paper, introduce the fountain code, LT code, BP code and Gauss code. Encode the packets and using different method to decode the packets. Compared BP code and Gauss code on successful decode rate, required time and overhead packets.
