摘要

摘要: 该文研究在阵列域大尺度衰落模型下，基站端天线仅仅配备了1-bit精度的模数转换器时大规模MIMO系统的性能。首先给出了系统采用最大比合并接收机时，用户上行可达速率的闭式表达式。然后分析了1-bit系统的功率效率性能，并将该1-bit系统与传统的具有无穷精度模数转换器的系统性能相比较。通过计算机仿真验证了该文的分析结果。该文指出基站端可以安装更多的天线来弥补1-bit精度的模数转换器所造成的性能损失。

Abstract: Based on the large scale fading channel model in antenna-array domain, this paper investigates the uplink performance for a massive MIMO system, where each antenna is equipped with one-bit Analog-to-Digital Converters (ADCs). A closed-form expression for the uplink achievable rate with Maximum Ratio Combining (MRC) receiver is derived, and the power efficiency performance, as well as the comparison between the one-bit systems and the conventional system with infinite resolution ADCs are investigated. Numerical results are presented to verify the analytical results.
