“…For mmWave systems under adjacent carrier interference, we thus wish to understand the fundamental relation between power consumption and interference tolerance and how this trade-off can be best optimized. Towards this end, the contributions of the paper are three-fold: First, building on the work in [3], [4], [27], [28], we provide a general methodology for mathematically analyzing the sensitivity of receivers from adjacent carrier emissions. Importantly, the framework can incorporate general power spectral densities of the interfering signals, models of the filters at various points in the receiver chain, as well as non-linearity and quantization limits in the analog front-end.…”

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-ofband interference. The goal is to elucidate the fundamental tradeoff 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.
