| Outline of Final Research Achievements |
To support the high capacity demands of wireless communication systems, high frequency band will be utilized in the near future. In this high frequency band, the effect of Doppler spread will become more significant and need to be carefully tackled. In this research, a beamforming technique is employed to reduce the Doppler spread which occurs at the mobile station. To give a more realistic channel model, the channel impulse responses are generated through a 3D ray launching method. The performance of this scenario is then evaluated through computer simulations.
