Part 1: Massive MIMO Fundamentals
Chapter 2: Channel Models for Large Arrays
Intermediate~220 min
Learning Objectives
- Characterize i.i.d. Rayleigh channels statistically and identify the conditions under which they are valid
- Construct spatial covariance matrices for the one-ring, Kronecker, and Weichselberger models
- Transform a physical MIMO channel to the angular (virtual) domain using the DFT matrix and interpret sparsity
- Describe the 3GPP TR 38.901 channel generation procedure and its key parameters
- Contrast sub-6 GHz and mmWave propagation from a massive MIMO design perspective
- Explain why channel model choice critically affects the design of pilot sequences, precoders, and receivers
