Chapter 16: MIMO II: Space-Time Coding and Transceiver Architectures

Learning Objectives

• Apply the rank and determinant criteria to design space-time codes that achieve full diversity and high coding gain
• Describe the V-BLAST and D-BLAST spatial multiplexing architectures and explain their layer-detection ordering strategies
• Compare MIMO receiver architectures (ML, ZF, MMSE, OSIC) in terms of performance, complexity, and diversity order
• Prove that MMSE-SIC achieves the MIMO channel capacity and relate it to decision-feedback equalisation
• Design linear and nonlinear precoding strategies (MRT, ZF, MMSE, dirty paper coding) when channel state information is available at the transmitter
• Quantify the capacity loss from limited feedback and design Grassmannian codebooks for precoding with finite-rate feedback
• Select appropriate MIMO transceiver architectures for given channel conditions, antenna configurations, and CSI availability
