The impact of noise on detecting the arrival angle using the root-WSF algorithm
This article discusses three standards of Wi-Fi: traditional, current and
next-generation Wi-Fi. These standards have been tested for their ability to detect the arrival angle of a noisy system. In this study, we chose to work with an intelligent…
