Chapter 12: MIMO Detection

Learning Objectives

• Formulate the MIMO detection problem and recognize why exact ML is exponential in the number of transmit antennas
• Derive the Zero-Forcing and MMSE linear detectors and compute their post-detection SINRs
• Understand Successive Interference Cancellation (V-BLAST), the role of ordering, and why MMSE-SIC achieves MIMO capacity
• Implement sphere decoding with Schnorr-Euchner enumeration and analyze its expected complexity
• Use the LLL algorithm to reduce a channel basis and build lattice-reduction-aided near-ML detectors
