Short Biography

Angel Lozano is a Professor of Information and Communication Technologies at UPF (Universitat Pompeu Fabra) in Barcelona, Spain, where he teaches and conducts research on wireless communications as head of the WiCom (Wireless Communications) Group. Born in Manresa, Spain, Angel Lozano received the Telecommunications Engineering degree from UPC (Universitat Politecnica de Catalunya), Spain, in 1992 and Master of Science and Ph.D. degrees in Electrical Engineering from Stanford University in 1994 and 1998, respectively. Contemporarily, between 1996 and 1998, he also worked for Rockwell Communication Systems (now Conexant Systems) in San Diego, USA. In 1999 he joined Bell Labs (Lucent Technologies, now Alcatel-Lucent) in Holmdel, USA, where he was a member of the Wireless Communications Department until 2008. Between 2005 and 2008 he was also an Adjunct Associate Professor of Electrical Engineering at Columbia University. Dr. Lozano is a senior member of the IEEE since 1999. He served as associate editor for the IEEE Transactions on Communications between 1999 and 2009, has guest-edited various other IEEE and non-IEEE journal special issues, and he is actively involved in committees and conference organization tasks for the IEEE Communications Society. He has further participated in standardization activities for 3GPP, 3GPP2, IEEE 802.20 and the IETF. Dr. Lozano has authored over 80 technical journal and conference papers, holds 15 patents, and has contributed to several books. His papers have received two awards: the best paper at the 2006 IEEE Int’l Symposium on Spread Spectrum Techniques & Applications, and the Stephen O. Rice prize to the best paper published in the IEEE Transactions on Communications in 2008. He has held visiting appointments at Stanford University, at the University of Minnesota, and at Universidad Tecnica Federico Santa Maria in Valparaiso, Chile.

Demonstrators

• Participated in the first demonstration of out-of-cell MIMO interference cancellation at the 2003 IST European Summit in Aveiro, Portugal, in June 2003. The demonstrator consisted of two commercial Lucent Technologies base stations, fitted for MIMO transmission using up to 4 antennas, and two mobile station prototypes equipped with 4 receive antennas each. The baseband processing boards on each of these prototypes featured original MIMO ASIC chips. Live video was streamed from each base station down to a respective mobile, with cross-interference between the transmissions. At each mobile station, the MIMO ASIC cancelled the interference from the undesired base while detecting the signal from the serving base.
