The Performance Analysis of LT Codes

LT codes are designed for the purpose of scalable and fault-tolerant distribution of data over wireless networks. This paper introduces the four design methods of LT codes degree distribution. Analyzing and comparison results of the short and long of LT code performance under the different channel probability are given, which show that in the case of large delete the probability, the original data packets can be recovered with high probability as long as the decoder receives a sufficient number of packets. The results of this paper will reference for system choose a different LT code parameters.
