Chapter 8: OTFS Detection

Learning Objectives

• Recognize ML detection as the optimal benchmark and why it is infeasible for large grids
• Derive the linear MMSE detector in the DD domain and its complexity
• Implement the message-passing (MP) detector on the DD factor graph
• Understand the low-complexity DD-domain (LCD) detector and its trade-offs
• Integrate channel decoding with OTFS detection via iterative soft-output schemes
