Channel Models for Performance Evaluation - Part II — Lesson 2

This lesson covers the concept of coverage probability and how it can be calculated using these models. It further discusses the International Mobile Telecommunications-2020 (IMT-2020), also known as 5G, and the path loss exponent used in its evaluation models. This lesson also covers the small scale fading model and fluctuations. The lesson concludes with an overview of small scale fluctuations and their impact on the channel structures.
