论文摘要
在这项工作中，我们考虑了一个大型多型多输入多输入（MIMO）蜂窝网络，该网络具有低分辨率类似于数字化的转换器（ADC）和数字到Analog转换器（DACS）。我们的第一个贡献是提出一个统一的前向链接分析框架，在该框架上，在通道硬化下的FD基站（BSS）应用了匹配的滤波器预编码器。其次，我们得出了一般和特殊情况和特殊情况的信号对量化 - 加工 - 加上噪声比（SQIinr）的表达式。最后，我们量化了识别误差，试点污染和完全复式的六角形细胞晶格对光谱效率和累积分布函数（CDF）的影响，以表明FD在各种情况下都超过了半双链（HD）。
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 digital-to-analog converters (DACs). Our first contribution is to propose a unified framework for forward link analysis where matched filter precoders are applied at the FD base stations (BSs) under channel hardening. Second, we derive expressions for the signal-to-quantization-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.
