基于链路自适应的协作编码部分重传机制研究
Cooperative coded partial retransmission scheme based on link adaptive technology
摘要
Abstract
In this paper, the cooperative Coded Partial(CPR) Retransmission scheme based on link adaptive technique is proposed. Utilizing the link state information at the relay node, the optimized-modulation and code mode of relay node is chosen. The simulated results show that Bit Error Rate( BER) performance of the proposed system is improved without sacrificing the system throughput. The BER of the proposed scheme has about 4. 5 dB gains compared with that of the direct transmission at throughput of 0. 19, Moreover, the proposed scheme obtains about 2 dB compared with the non-adaptive scheme at BER of 10-3.关键词
