基于平均频谱效率的自适应编码调制优化设计

Optimal Design of ACM Based on Average Spectral Efficiency

自适应编码调制(ACM)技术能够很好地改善无线信道的频谱利用率。文中提出了一种基于平均频谱效率的自适应调制编码系统的优化方案,运用该方案,ACM系统需要数量很少的优化编码,使吞吐量接近于AWGN信道容量。

Adaptive coded modulation （ACM） is an effective way to promote spectral efficiency in wireless channels. This paper presents an optimal design scheme of adaptive coded modulation based on average spectral efficiency. Using this method, ACM system needs only a small number of optimally designed codes, thus making the throughout close to the capacity of AWGN.
