摘要
在协作网络编码的解码转发方案的基础上,提出了基于协作网络编码DF与AF的机会协作通信方案,在这个方案中,用户根据与协作伙伴间的瞬时信道状态信息,决定如何处理接收到的协作伙伴的信息。若信道状态信息满足用户能够正确解码的要求,则采用协作网络编码DF方案,对接收到的信息与本地信息进行叠加发送给基站,否则采用AF方案,对接收到的信息进行放大,转发给基站。并研究得到了该方案的中断概率,通过仿真论证得到,该方案能够有效的降低系统的中断概率。
A opportunistic cooperative strategy based on cooperative network coding – DF and AF is proposed.In the strategy,how to dispose the information received from cooperated partner is determined by the immediate channel condition.Then,the received information which is correctly decoded is coding by network code and transmitted to the base station,else it is amplified and transmitted to the base station.The outage probability is also analyzed,and the numerical results show that the proposed scheme can reduce outage probability of cooperative network coding systems effectively.
