It isknown that Luby Transform code LT code is the first code fully realizing thedigital fountain concept and provides an efficient scheme to transferinformation over different channels. The key to make LT code work well is the degreedistribution used in the encoding procedure. It determines the degree of each encodingsymbol. Onthe basis of robust solition distribution and optimized degree distribution, anovel degree distribution which has only one parameter is proposed in thispaper. Through computer simulation, the performance of LT code with the noveldegree distribution is better than the robust solition distribution and sparse degreedistribution. Theconclusion of the researchis practically valuable in improving the efficience of data distribution application.
