摘要

全数字大规模多输入多输出（multiple-input multiple-output，MIMO）系统因具有低成本、信号处理能力强、可灵活配置等优势，在移动通信中有很广泛的应用前景。在研究一比特sigma-delta调制结构的基础上，分析了系统的遍历可达频谱效率，并仿真对比了一比特结构。结果表明一比特sigma-delta调制结构具有更高的频谱效率，适用于大规模MIMO系统，并且分析结果是精确的。

Abstract

The all-digital massive multiple-input multiple-output (MIMO) system has a wide range of application prospects in mobile communication due to its advantages such as low cost

strong signal processing capability

and flexible configuration. On the basis of studying the one-bit sigma-delta modulation structure

the ergodic achievable spectral efficiency of the system was analyzed and compared with the one-bit structure through simulation. The results show that the one-bit sigma-delta modulation structure has higher spectral efficiency

is suitable for massive MIMO systems

and the analysis results are accurate.
