Metasurface-Based Receivers with 1-bit ADCs for Multi-User Uplink Communications
CoRR(2024)
摘要
The massive Multiple-Input Multiple-Output (mMIMO) concept has been recently
moving forward to extreme scales to address the envisioned requirements of next
generation networks. However, the extension of conventional architectures will
result in significant cost and power consumption. To this end,
metasurface-based transceivers, consisting of microstrips of metamaterials,
have recently emerged as an efficient enabler of extreme mMIMO systems. In this
paper, we consider metasurface-based receivers with a 1-bit Analog-to-Digital
Converter (ADC) per microstrip and develop an analytical framework for the
optimization of the analog and digital combining matrices. Our numerical
results, including comparisons with fully digital, infinite-resolution MIMO,
provide useful insights into the role of various system parameters.
