A beam codebook of 5G millimeter wave (mmWave) for data communication consists of multiple high-peak-gain beams to compensate the high pathloss at the mmWave bands. These beams also have to point to different angular directions, such that by performi

The 60 GHz Wi-Fi based on the IEEE s802.11ad standard has been attractive for recent years due to the high potential of the large bandwidth in 60 GHz unlicensed band allowing the multi-gigabit data transfer. However, the commercialization 60 GHz Wi-F

This paper presents a method to track multiple moving humans using Ultra-Wideband (UWB) radar. UWB radar can complement other human tracking technologies, as it works well in poor visibility conditions. Our tracking approach is based on a point proce
