| Abstract: | On the base of analyzing the coding and decoding mechanism, this paper explores more deeply by discussing the influence of choosing interleaving depth (block length), interleaving alphabet, decoding algorithm, etc. Besides, we compare the performance with RS code and convolutional code with viterbi decoding. Furthermore, we will discuss some inspirations which turbo code brings to the research in future. |
