Abstract
A new memory based LT encoding scheme is proposed to improve communication reliability and decrease latency at the same time. The robust Soliton distribution (RSD) is shifted as the output symbol degree distribution in the proposed method. The input symbol degree distribution is also changed based on memory. Analysis shows the proposed method has faster decoding convergence speed than the conventional memory based LT code. Simulation results validate the analysis and show BER performance. Compared with regular LT code and the conventional memory based LT code, the proposed method has better BER performance.
