摘要/Abstract

摘要： 提出了一种基于ACK/NAK的AMC/HARQ算法。利用ACK/NAK信息控制调制编码方式,从而不再需要C/I反馈。文中分析了算法在静态信道下的收敛性能和吞吐率性能,并通过仿真给出了时变衰落信道下的吞吐率。本算法与有一定C/I反馈误差的基于C/I的AMC/HARQ相当。对于反向容量受限的情形,采用本算法可以简化系统设计,并可节约反向容量。

Abstract: A novel adaptive AMC/HARQ scheme is proposed. The scheme makes use of ACK/NAK information to control the modulation/coding format, hence the C/I information feedback is no more required. The convergence and throughput performance in staticchannel is analyzed and the simulated performance for time varying fading channel is shown. The performance of the proposed scheme is comparable to the conventional C/I based AMC/HARQ where the C/I information known to the transmitter is not accurate. With the proposed scheme, the system design can be simplified and the reverse link capacity can be saved in case where the reverse link capacity isscarce.

Key words: adaptive modulation/coding, hybrid-ARQ, ACK
