论文摘要
功耗是毫米波（MMWave）接收器前端的关键挑战，因为需要在宽带宽处支撑高维天线阵列。最近，通常基于低分辨率ADC和低功率搅拌机，开发低功率前端的工作已经大量工作。这种设计的关键但较少研究的结果是相对较低的动力范围，进而将接收器暴露于相邻的载体干扰和阻滞剂。本文提供了一个一般的数学框架，用于分析在带外干扰的情况下MMWave前端的性能。目的是阐明功耗，干扰耐受性和频段性能的基本权衡。该分析与具有多个载体的细胞系统中的详细网络模拟以及140 GHz的关键组件的详细电路模拟结合使用。该分析揭示了低功率干扰鲁棒性的关键瓶颈，并建议在实用系统中使用设计增强功能。
Power consumption is a key challenge in millimeter wave (mmWave) receiver front-ends, due to the need to support high dimensional antenna arrays at wide bandwidths. Recently, there has been considerable work in developing low-power front-ends, often based on low-resolution ADCs and low-power mixers. A critical but less studied consequence of such designs is the relatively low-dynamic range which in turn exposes the receiver to adjacent carrier interference and blockers. This paper provides a general mathematical framework for analyzing the performance of mmWave front-ends in the presence of out-of-band interference. The goal is to elucidate the fundamental trade-off of power consumption, interference tolerance and in-band performance. The analysis is combined with detailed network simulations in cellular systems with multiple carriers, as well as detailed circuit simulations of key components at 140 GHz. The analysis reveals critical bottlenecks for low-power interference robustness and suggests designs enhancements for use in practical systems.
