论文摘要
使用低分辨率模拟对数字转换器（ADC）的使用是减少毫米波（MMWave）接收器的高功耗的有效方法。在本文中，在下行链路MMWave通信中考虑了基于自适应阈值的低分辨率ADC的接收器，在该通道中，频道状态信息不知道A-Priori并通过频道估计获得。分别提供了发射和接收终端之间的功率和ADC分配的低复杂性算法的性能比较。通过模拟实用的MMWave蜂窝网络，可以证明，低分辨率ADC的使用不会显着降低系统吞吐量（与常规的全数字高分辨率接收器相比），当使用自适应阈值接收器与简单的功率和ADC分配策略结合使用。
Use of low resolution analog to digital converters (ADCs) is an effective way to reduce the high power consumption of millimeter wave (mmWave) receivers. In this paper, a receiver with low resolution ADCs based on adaptive thresholds is considered in downlink mmWave communications in which the channel state information is not known a-priori and acquired through channel estimation. A performance comparison of low-complexity algorithms for power and ADC allocation among transmit and receive terminals, respectively, is provided. Through simulation of practical mmWave cellular networks, it is shown that the use of low resolution ADCs does not significantly degrade the system throughput (as compared to a conventional fully digital high resolution receiver) when using the adaptive threshold receiver in conjunction with simple power and ADC allocation strategies.
