The performance of the hybrid beamforming system with the number of radio frequency(RF) chains and the accuracy of shifters is studied. And compare it with the performance of digital beamforming. The simulation results show that the performance of hybrid beamforming can approach the performance of digital beamforming system with less RF links and lower phase shifter accuracy. %U https://journal.bupt.edu.cn/EN/10.13190/j.jbupt.2018-194
