该论文提出了一种用于毫米波相控阵的最优数字波束成形器,在28nm CMOS工艺中实现了660MHz瞬时带宽,解决了毫米波通信中路径损耗大、干扰严重导致的信干噪比下降问题。
University of Washington, Seattle, WA Ever-increasing global demand for communication bandwidth is incentivizing broader use of the millimeter wave (mm-Wave) frequency band which operates with carrier frequencies exceeding 28GHz [1]. However, such communication poses significant challenges including increased path loss, limited antenna aperture and interference from other transmitters which severely degrades the Signal-to-Interference-plus-Noise Ratio (SINR) of the communication channel. To overcome these challenges, mm-Wave systems employ phased antenna arrays to implement beamforming (BF). Figure 16.7.1 shows a simplified overview of receive beamforming for a single incident signal which involves applying suitable gain (gk) scaling and phase-shift (e jθk) to the successively delayed signals received at each antenna element before combining them. Doing so constructively superposes, and therefore
