| Abstract(in English) | The performance of LT (Luby Transform) codes depends on degree distributions. In this study, we propose a new degree distributions, which combines the Robust Soliton distribution and the Heavy tail distribution with the upper limit parameter $D$, to improve the performance of LT codes. The simulation results show that the proposed degree distributions has better decoding performance than the Robust Soliton distribution for various number of input symbols. |
