Energy Efficient ADC Bit Allocation and Hybrid Combining for Millimeter Wave MIMO Systems

26 Sep 2019 Kaushik Aryan Tsinos Christos Vlachos Evangelos Thompson John

Low resolution analog-to-digital converters (ADCs) can be employed to improve the energy efficiency (EE) of a wireless receiver since the power consumption of each ADC is exponentially related to its sampling resolution and the hardware complexity. In this paper, we aim to jointly optimize the sampling resolution, i.e., the number of ADC bits, and analog/digital hybrid combiner matrices which provides highly energy efficient solutions for millimeter wave multiple-input multiple output systems...
