A Distributed Fountain Code for Cooperative Communications
Zhu Kai-ya · Dianzi xuebao · 2014
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.
