Plenary Session: PLEN-4: Robert Heath - "What Is Next in Signal Processing for MIMO Communication?"

In the last 20 years, MIMO wireless communication has gone from concept to commercial deployments in millions of devices. Two flavors of MIMO widely researched in the Signal Processing community -- massive and mmWave -- are key components of 5G. In this talk, I will explain why MIMO communication has remained such a vibrant topic of signal processing research especially as systems have gone to millimeter wave and higher carrier frequencies. Then I will speculate on several directions for future MIMO research. I will talk about how other advancements in circuits, antennas, and materials may change the models and assumptions that are used in MIMO signal processing, leading to new algorithms and signal processing developments in the future.
