A novel degree distribution algorithm of LT codes

This paper proposed the optimal degree distribution algorithm of LT codes and analyzed its drawbacks in realization. On the basis of the optimal degree distribution algorithm, a novel suboptimal degree distribution algorithm was put forward. Through test, with respect to the average decoding efficiency, the best decoding efficiency and the variance of decoding efficiencies, the LT codes with suboptimal degree distribution algorithm performs better than that with robust soliton degree distribution algorithm. The conclusion of research is practically valuable in improving efficiencies of data distribution applications.
