This chapter investigates how multiple-antenna systems address challenges in wireless channels experiencing multipath propagation and fading, extending previous work on line-of-sight conditions. It analyzes receive diversity techniques like selection combining, equal gain combining, and maximal ratio combining using a simple receiver with multiple antennas. Next, it explores information theoretic limits on achievable data rates and the trade-off between data rate and reliability. An overview of transmit diversity schemes is then provided. The chapter also covers the basics of to multiuser MIMO systems, and discusses various interference mitigation techniques. It also discusses various interference mitigation techniques. Finally, it introduces massive MIMO systems, their practical implementation, and their impact on link budgets.
