为了减少基于数字喷泉码的协作传输系统中的计算复杂度和传输延迟,提出了一种基于分布式喷泉码的协作通信传输方案,给出了两层数字喷泉编码的度分布函数的设计过程;以各链路的丢包率为参量分析了系统传输时延,并与其他数字喷泉码传输方案进行了比较.理论分析和仿真结果表明,在各链路丢包率较大时采用这种分布式喷泉码的协作传输机制能在传输时延上显著改善系统性能,而且各链路删除概率越大时优势越明显.
In order to reduce computation complexity and latency in cooperative communication system based on fountain code
a distributed fountain code based cooperative transmission scheme was proposed.The design of two layer degree distribution was presented.The transmission latency for the distributed fountain code based cooperative transmission scheme and other conventional fountain code based transmission schemes was analyzed and compared.Results show that the total time consumed under the distributed fountain code based scheme can be significantly reduced compared to conventional fountain code based direct transmission and cooperative transmission when the packet erasure rate is big.With the increase of packet erasure rate
the advantage of the distributed fountain code based scheme is more evident.
