Who is Hamid Jafarkhani?

Hamid Jafarkhani, born in 1966 in Tehran, is a Chancellor's Professor in electrical engineering and computer science at the University of California, Irvine's Henry Samueli School of Engineering. His research focuses on communications theory, particularly coding and wireless communications and networks.

Prior to studying at the University of Tehran, he was ranked first in the nationwide entrance examination of Iranian universities in 1984. After receiving his B.S. degree in 1989, he studied at the University of Maryland College Park and obtained his M.S. degree in 1994 followed by his Ph.D. in 1997. 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 for his contributions to two seminal papers which established the field of space–time block coding, published whilst working for AT&T. The first of these, "Space–time block codes from orthogonal designs", established the theoretical basis for space–time block codes and the second, "Space–time block coding for wireless communications: performance results", provided numerical analysis of the performance of the first such codes. Space–time codes rely on the use of multiple antennas at the transmit side of a wireless link. Multiple copies of the same data are transmitted from these multiple antennas in such a way that the receiver has a much better chance of correctly detecting the signal in the presence of corruption and noise than if just one copy is sent. The performance of space–time coded systems, in terms of the reliability of the transmission is significantly better than non-coded systems. Space–time block codes in particular are known to be simple to implement and effective, and Jafarkhani's two papers triggered the massive international research effort into them that continues today.
