论文摘要
Sub-Terahertz(Sub-Thz)天线阵列体系结构显着影响多用户多输入多输出(MU-MIMO)系统中的功率使用和通信能力。在这项工作中,我们比较了基本站接收器的三个MU-MIMO阵列架构的能效和光谱效率。我们根据对最先进的D波段和G频段组件的审查提供了Sub-Thz电路电源分析,并通过宽带模拟比较通信功能。我们的分析表明,由于Sub-THZ主动相位变速器的功率高,或者SNR和系统频谱效率要求很高,数字阵列可以提供最高的光谱效率和能效。
Sub-terahertz (sub-THz) antenna array architectures significantly impact power usage and communications capacity in multi-user multiple-input multiple-output (MU-MIMO) systems. In this work, we compare the energy efficiency and spectral efficiency of three MU-MIMO capable array architectures for base station receivers. We provide a sub-THz circuits power analysis, based on our review of state-of-the-art D-band and G-band components, and compare communications capabilities through wideband simulations. Our analysis reveals that digital arrays can provide the highest spectral efficiency and energy efficiency, due to the high power consumption of sub-THz active phase shifters or when SNR and system spectral efficiency requirements are high.
