摘要:

无速率编码作为一种纠删码,在减少反馈重传的同时也具有码率灵活、编译码简单的特性,在许多领域都有广阔的应用前景。度分布作为无速率编码设计的基础,对无速率编码的性能有至关重要的影响。随着无速率编码的广泛应用,度分布的设计也需要随着场景和需求的变化进行优化。首先论述了无速率编码的发展与应用,从几种经典的无速率编码和度分布开始,详细地从应用场景、优化目标以及现有优化方法 3 个角度,对目前无速率编码中度分布的研究和发展进行了总结与分析。最后,对无速率编码和度分布的发展应用趋势进行了分析与展望。

Abstract:

As a kind of deletion coding technology, the rateless code reduces feedback retransmission and has the characteristics of flexible bit rate and simple compilation code, which has broad application prospects in many fields.As the basis of rateless code design, degree distribution has a crucial impact on the performance of the rateless code With the wide application of the rateless code, the design of degree distribution also needs to change with changes in scenarios and needs.Firstly, the development and application of the rateless code were discussed.Starting with several classical rateless codes and degree distributions, the current research and development of the degree distribution were summarized and analyzed from three perspectives of application scenarios, optimization targets and existing optimization methods.Finally, the development and application trend of rateless codes and degree distribution were discussed.

Key words: rateless code, fountain code, degree distribution, network coding, multipath
