中文摘要：

由于具有良好的信道自适应和低反馈数据量的优点,非恒速码有很好的应用前景.然而由于其自身编码的特点会造成数据传输延时,加上其对反馈链路质量的好坏敏感,直接影响了它在实时数据传输业务方面的应用.研究了随机反馈的ACK延时对非恒速编码性能的影响,提出一种新的LT编码实时数据传输策略,以解决传输系统实际反馈链路的非理想状况对通信质量造成的影响,实现了反馈不可靠情况下LT码的实时数据传输.

英文摘要：

Rateless codes has the advantage of good channel adaptivity with a low amount of feedback data.However,the data transmission delay caused by its own coding characteristics and its sensitivity of the feedback link quality directly affects its application in real-time data transmission services.The random delay of feedback ACK which reduce the LT coding＇s performance was discussed,and then a new LT code based real-time transmission strategy was proposed to address the impact of non-ideal conditions of the feedback link.This strategy can achieve higher data throughout in non-ideal feedback conditions.
