Hamid Jafarkhani (Persian: حمید جعفرخانی) (born 1966, in Tehran) is an Iranian-born American electrical engineer and professor.
After graduating, Jafarkhani joined AT&T Laboratories-Research in August 1997 before moving to Broadcom in July 2000 and to the University of California, Irvine in September 2001.
Within the wireless communications field, Jafarkhani is best known as the primary/main inventor of space-time codes (jointly with Siavash Alamouti and Nambirajan Seshadri) [1] and for his two seminal papers[2][3] which established the field of space–time block coding, published whilst working for AT&T.
Space–time block codes in particular are known to be simple to implement and effective, and Jafarkhani's ideas in these two papers triggered the massive international research effort into them that continues today.
Jafarkhani is a co-recipient of the 2013 IEEE Eric E. Sumner Award for outstanding contributions to communications technology.
