论文摘要
我们考虑具有密集的平面阵列的无线通信系统，具有密度间隔的天线元件以及一位类似物到数字和数字 - 数字到Analog转换器（ADC/DACS）。我们通过为上行链路以及下行链路场景提供了可实现的速率的封闭式表达式，同时考虑了天线互耦合的影响。在下行链路情况下，我们介绍了非辐射抖动的概念，以打击量化错误的相关性。在较高的天线元件密度下，我们表明，无论操作信噪比如何，量化系统的性能都可以接近理想性能。
We consider wireless communication systems with compact planar arrays having densely spaced antenna elements in conjunction with one-bit analog-to-digital and digital-to-analog converters (ADCs/DACs). We provide closed-form expressions for the achievable rates with simple linear processing techniques for the uplink as well as the downlink scenarios while taking into account the effects of antenna mutual coupling. In the downlink case, we introduce the concept of non-radiating dithering to combat correlations of the quantization errors. Under higher antenna element density, we show that the performance of the quantized system can be made close to the ideal performance regardless of the operating signal-to-noise ratio.
