Understanding Mobile Radio Propagation-10 — Lesson 10

This lesson covers the concept of mobile radio propagation with a focus on channel measurements. It begins with a recap of previous lectures and then delves into a case study of ultra-wideband communication to understand how channel model measurements can be done for UWB scenarios. The lesson discusses existing channel models for ultra-wideband communications and explores different channel measurement campaigns. It also explains the techniques of measuring channels either in the time domain or the frequency domain. The lesson concludes with a brief discussion on the channel measurement campaign carried out at Intel and some in-house IIT Delhi channel measurement data.
