摘要/Abstract

摘要： 提出了一种基于V-BLAST系统的跨层设计方案，综合考虑物理层的自适应调制和链路层的截短ARQ技术，推导了平坦衰落信道下的频谱效率和中断率。数据仿真结果表明，这种联合设计可以降低V-BLAST系统的中断率，并且获得可观的频谱效率增益。

Abstract: The combination of adaptive modulation (AM) at physical layer and truncated automatic repeat request at data link layer in V-BLAST system is considered in this paper. We deduce the spectral efficiency and the outage probability from our proposed design over frequency-flat Rayleigh channels. Numerical results reveal that the joint design of AM and truncated ARQ in V-BLAST system can achieve considerable spectral efficiency gain and outage probability reduction.

Key words: Adaptive modulation (AM), Truncated automatic repeat request(T-ARQ), Vertical Bell-Labs layered space-time system (V-BLAST), Packet Error Rate (PER)
