论文摘要
我们考虑在新的无线电GNB捐赠者和单个用户设备之间以全双工模式运行的宽带集成访问和回程系统。由于毫米波系统的高功耗，我们在接收器中使用低分辨率类似物转换器（ADC）。我们的贡献包括（1）混合束缚器，以取消自我干扰和最大化接收的功率来最大化访问和回程链接的总和光谱效率； （2）所有数字波束形式和上限频谱效率； （3）模拟比较完整与半双链，有限与无限ADC分辨率，混合和全数字波束成形以及上限的频谱效率。
We consider a wideband integrated access and backhaul system operating in full-duplex mode between the New Radio gNB donor and single user equipment. Due to high power consumption in millimeter wave systems, we use low-resolution analog-to-digital converters (ADCs) in the receivers. Our contributions include (1) hybrid beamformer to maximize sum spectral efficiency of the access and backhaul links by canceling self-interference and maximizing received power; (2) all-digital beamformer and upper bound on sum spectral efficiency; and (3) simulations to compare full vs. half duplex, finite vs. infinite ADC resolution, hybrid vs. all-digital beamforming, and the upper bound in spectral efficiency.
