“…where F is the precoder. As the additive to quantization plus noise model (AQNM) approximates the quantization error [5], [6], [18], [19], the received y u q and transmitted signals x d,q after the ADC/DAC at the BS can be obtained by y u q = α u y u + q u (4)…”

In this work, we consider a full-duplex (FD) massive multiple-input multiple-output (MIMO) cellular network with low-resolution analog-to-digital converters (ADCs) and digitalto-analog converter (DACs). Our first contribution is to provide a unified framework for reverse link analysis where matched filters are applied at the FD base stations (BSs) under channel hardening. Second, we derive the expressions of the signal-toquantization-plus-interference-plus-noise ratio (SQINR) for general and special cases. Finally, we quantify effects of quantization error, pilot contamination, and full duplexing for a hexagonal cell lattice on spectral efficiency and cumulative distribution function (CDF) to show that FD outperforms half duplex (HD) in a wide variety of scenarios.
