CIR-Based Device-Free People Counting via UWB Signals

WebUltra-wideband, or UWB, is a short-range RF technology for wireless communication that can be leveraged to detect the location of people, devices, and assets with unrivaled precision. Like other communication protocols including Bluetooth and Wi-Fi, UWB can be used to transmit data between devices through radio waves. WebThe channelizer splits a wide bandwidth into smaller ones to separate signals of interests from noise and interferers so that low SNR and time sensitive signals can be reliably detected in individual subchannels. Most digital channelized receivers consist of a filter bank and fast Fourier transform (FFT). WebWhat are the benefits of 5G Ultra Wideband?
