Robert W. Heath Jr. is an American electrical engineer, researcher, educator, wireless technology expert, and a professor in the Department of Electrical and Computer Engineering at the University of California, San Diego. [1] He is also the president and CEO of MIMO Wireless Inc. He was the founding director of the Situation Aware Vehicular Engineering Systems initiative. [2]
Heath received his Ph.D. in electrical engineering from Stanford University in 2002 under the supervision of MIMO pioneer Arogyaswami Paulraj. [3] He completed his M.S. degree in the same field from the University of Virginia in 1997 under the supervision of Georgios B. Giannakis, [4] and his B.S. in electrical engineering from the University of Virginia in 1996.
From 1998 to 2001, Heath was a Senior Member of the Technical Staff and, later, Senior Consultant at Iospan Wireless Inc, San Jose, CA. At Iospan he was part of a team that designed and implemented the physical and link layers of the first commercial MIMO-OFDM communication system. From January 2002 to August 2020, he was with the Department of Electrical and Computer Engineering at The University of Texas at Austin where he was a Cockrell Family Regents Chair in Engineering. He is also President and CEO of MIMO Wireless Inc. and Chief Innovation Officer at Kuma Signals LLC. [5] He was the Director of the Wireless Networking and Communications Group from 2012-2014, where he oversaw an expansion of the center in terms of faculty and students, and an increase in research expenditures to more than $5M per year. At UT he also founded an initiative that brings together transportation and communications called the Situation-Aware Vehicular Engineering Systems (SAVES). [2] He was a Distinguished Professor at the North Carolina State University from October 2020 to December 2023. He is currently a professor at the University of California, San Diego. He is a co-author on more than 600 refereed conference and journal publications. [6] He is also a co-inventor of 64 U.S. patents. He authored a laboratory manual that teaches the principles of wireless communication to undergraduate students [7] and co-authored a book on millimeter wave wireless communication. [8] He authored a book on wireless digital communications [9] and co-authored a comprehensive textbook on MIMO communications [10] He is particularly known for his work on different aspects of MIMO communication systems and millimeter-wave communications. [11]
Heath's early work at Stanford advanced the then nascent field of MIMO communication. [12] [13] During his Ph.D. he took a leave of absence to be one of the first employees at Iospan Wireless (earlier known as Gigabit Wireless Inc), where he was part of a small team that created the first practical MIMO-OFDM radio (a predecessor of what we now know as IEEE 802.11n). [14] His work at Iospan resulted in several early patents on critical MIMO technologies. [15] [16] [17]
Heath's work at Iospan led to his discovery that, depending on the wireless propagation conditions, different MIMO configurations, e.g., spatial multiplexing or space-time coding, are preferred. [18] [19] [20] Heath's discovery opened new research avenues to enhance the fundamental understanding of performance limitations in MIMO wireless communication. [21] From his diversity and multiplexing discovery, he also recognized the critical importance of feedback and adaptation in MIMO wireless systems, i.e., to make MIMO wireless communication commercially viable the receiver must inform the transmitter about the best MIMO configuration before communication [22]
At UT Austin, based on his insights into the importance of feedback in MIMO communication, he pioneered MIMO feedback strategies (limited feedback precoding).[ citation needed ] Heath was able to construct a strategy for which the overhead penalty for feedback was very small (only a few bits of feedback required to configure an entire MIMO transmitter). This allowed practical MIMO wireless communication to achieve data rates and link reliability very close to theoretical expectations by varying the number of spatial multiplexing streams.[ citation needed ]
Heath is an advocate of moving to millimeter-wave spectrum for the 5G cellular standardization. He recognizes, however, that 5G cellular deployments will likely require significant changes to cellular planning. He has predicted that, due to blockage, millimeter wave cellular will need to be much more densely deployed. [44] [45] Heath also recognizes that 5G cellular will require significant advancements in beamforming protocols, in particular with respect to the speed in which beamforming is trained, to make 5G cellular at millimeter waves viable. He has been a strong advocate of the automotive application for 5G. [46]

Multi-user MIMO (MU-MIMO) is a set of multiple-input and multiple-output (MIMO) technologies for multipath wireless communication, in which multiple users or terminals, each radioing over one or more antennas, communicate with one another. In contrast, single-user MIMO (SU-MIMO) involves a single multi-antenna-equipped user or terminal communicating with precisely one other similarly equipped node. Analogous to how OFDMA adds multiple-access capability to OFDM in the cellular-communications realm, MU-MIMO adds multiple-user capability to MIMO in the wireless realm.
In radio, multiple-input and multiple-output (MIMO) is a method for multiplying the capacity of a radio link using multiple transmission and receiving antennas to exploit multipath propagation. MIMO has become an essential element of wireless communication standards including IEEE 802.11n, IEEE 802.11ac, HSPA+ (3G), WiMAX, and Long Term Evolution (LTE). More recently, MIMO has been applied to power-line communication for three-wire installations as part of the ITU G.hn standard and of the HomePlug AV2 specification.

The first smart antennas were developed for military communications and intelligence gathering. The growth of cellular telephone in the 1980s attracted interest in commercial applications. The upgrade to digital radio technology in the mobile phone, indoor wireless network, and satellite broadcasting industries created new opportunities for smart antennas in the 1990s, culminating in the development of the MIMO technology used in 4G wireless networks.
Multiple-input, multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) is the dominant air interface for 4G and 5G broadband wireless communications. It combines multiple-input, multiple-output (MIMO) technology, which multiplies capacity by transmitting different signals over multiple antennas, and orthogonal frequency-division multiplexing (OFDM), which divides a radio channel into a large number of closely spaced subchannels to provide more reliable communications at high speeds. Research conducted during the mid-1990s showed that while MIMO can be used with other popular air interfaces such as time-division multiple access (TDMA) and code-division multiple access (CDMA), the combination of MIMO and OFDM is most practical at higher data rates.

Per-user unitary rate control (PU2RC) is a multi-user MIMO (multiple-input and multiple-output) scheme. PU2RC uses both transmission pre-coding and multi-user scheduling. By doing that, the network capacity is further enhanced than the capacity of the single-user MIMO scheme.
