摘要

度分布是设计LT代码的核心。它影响着LT码的编解码复杂度和误码性能。本文对井设计LT规范的平均度、释放概率、开销系数等指标进行了分析。它将比较鲁棒LT代码、次优LT代码和SF-LT代码之间的指标。此外，它还为如何设计一个设计良好的LT代码提供了一些数学指导。

Performance Analysis of LT Codes with Different Degree Distribution

Degree distribution lies at the heart of design an LT code. It affects the encoding and decoding complexity and error performance of LT code. In this paper, some metrics of well-design LT code such as average degree, release probability, overhead factor is analyzed. It will compare the metrics among robust LT code, sub optimal LT code and SF-LT code. Moreover, it provides some mathematical guideline on how to design a well designed LT code.
