Chapter 17: Cell-Free Massive MIMO with OTFS

Learning Objectives

• Define cell-free massive MIMO and its advantages over cellular MIMO
• Extend the OTFS channel model to distributed AP deployments
• Design pilot schemes for cell-free OTFS channel estimation
• Analyze conjugate beamforming in the DD domain at distributed APs
• Quantify the 35% gain in 95%-likely per-user throughput (CommIT contribution)
