- Abstract
- Millimeter wave technology is major candidate technology for 5G network. Because of the high path loss characteristics of the mmWave system, beamforming technique is necessary to overcome this high path loss. Beamforming technology cannot achieve perfect beam alignment and it leads to degradation of the channel gain between the transceiver. Thus, we examine a gain degradation effect due to beam misalignment on mmWave beamforming system. We generated the channel coefficients by using QuaDRiGa channel model implementation. The channel gain analysis results shows that the misalignment of the BS beam causes high channel gain degradation.
