Lecture
This lecture delves into the use of millimeter wave frequencies in 5G, focusing on the implementation of antenna arrays to compensate for signal attenuation. The instructor explains how directional antennas work in 5G and Wi-Fi 8.11 AD, detailing the channel equations and multipath profiles. By utilizing multiple antennas, the lecture demonstrates how to compute the power in different directions and correct for phase, ultimately optimizing signal reception.
