Yongzhao Lin, Chengke Wu, Qun Zhang, Wei Liu · 2009
For the problem of low code gain of the concatenation of Reed Solomon (RS) codes and convolutional codes (CC), the concatenated scheme of RS+CC and Luby transform (LT) codes with an improved decoding algorithm is proposed. The improved decoding algorithm for LT codes decreases the receiving buffer consumption and improves the successful decoding probability and the real-time property of LT codes at some low computational cost. Simulations and analyses are made to evaluate the performance of the concatenated scheme in terms of the error correction capacity and cost.
