IEEE Life Fellow Gerard J. “Jerry” Foschini, a Bell Labs researcher for more than 50 years, died on 17 September, 2023, at the age of 83.
Foschini made groundbreaking contributions to the field of wireless communications that improved the quality of networks and paved the way for several important IEEE standards.
In the early 1990s he helped to develop the multiple-input multiple-output (MIMO) method of using antennas to increase radio link capacity. A few years later he introduced the Bell Laboratories Layered Space-Time (BLAST) transceiver architecture, which advanced antenna systems by allowing multiple data streams to be transmitted on a single frequency.
Foschini’s work is set to be honored in Los Angeles at the Italian American Museum’s “Creative Minds” exhibit, which is designed to spotlight inventors and innovators. The exhibit is scheduled to run at the museum from next month until next October.
Decades of innovation at Bell Labs
Foschini received a bachelor’s degree in electrical engineering in 1961 from the New Jersey Institute of Technology, in Newark. He earned a master’s degree in EE in 1963 from New York University and went on to earn a Ph.D. in EE in 1967 from Stevens Institute of Technology, in Hoboken, N.J.
He began his career in 1961 as a researcher at Bell Labs, in Holmdel, N.J. (Bell Labs headquarters moved to nearby Murray Hill in 1967, but the Wireless Communications Lab remained in Holmdel.)

MIMO was one of his most well-known breakthroughs. Developed in the late 1980s, the technology became an essential element of wireless communication standards including IEEE 802.11n and IEEE 802.16 (known commercially as WiMAX). MIMO arrays can be found in many cellular and Wi-Fi systems.
In the mid-1990s Foschini helped develop BLAST. He coauthored the seminal 1998 paper “V-BLAST: An Architecture for Realizing Very High Data Rates Over the Rich-Scattering Wireless Channel” with fellow Bell Labs researchers Glenn Golden, Reinaldo A. Valenzuela, and Peter Wolniansky. A simplified version known as V-BLAST is a multiantenna communication technique that detects and repropagates the strongest signal and eliminates interference, enhancing the data quality of wireless networks.
Foschini retired in 2013.
An often-cited researcher
During his career, Foschini wrote more than 100 published works and was awarded 14 patents related to wireless communications technology. According to the Institute for Scientific Information (now part of Clarivate), Foschini was in the top 0.5 of 1 percent of publishing researchers. His works were cited more than 50,000 times.
He was elected to the U.S. National Academy of Engineering in 2009 for “contributions to the science and technology of wireless communications with multiple antennas for transmission and receiving.” He was honored with the 2008 IEEE Alexander Graham Bell Medal and the 2006 IEEE Eric E. Sumner Award.
A tribute published on the IEEE Communications Society website says:
“Although Jerry was modest and unassuming, his brilliance and deep insight became apparent as soon as one engaged him in a technical conversation. His kindness and grace permeated all his interactions. A great mentor to all his colleagues, Jerry was particularly inspiring to young researchers, eager to hear about their work and provide them with guidance and encouragement.”
