The theory (and practice) of wireless systems use a variety of math tools ranging from linear and multi-linear algebra, tensor algebra, Clifford algebra, Galois fields, lattice reduction, sphere decoding, message passing iterative methods, random matrix methods, etc. The math is often used to model behavior and determine fundamental limits to performance. Real modems reduce everything to add/subtract, multiply/divide and xor type operations. This talk (by an engineer) is aimed at giving mathematicians an imperfect peep into the world of wireless.

SPEAKER'S PROFILE: Professor Arogyaswami Paulraj is a pioneer of MIMO wireless communications, a technology break through that enables dramatically improved wireless performance. MIMO is now incorporated into all new wireless standards including WiFi, 3G and 4G. Paulraj is the author of over 400 research papers, two text books and a co-inventor in 51 US patents. He founded two companies - Iospan Wireless that laid the foundation for 4G wireless technologies and was acquired by Intel Corp.in 2003, and Beceem Communications that became a leader in 4G wireless semiconductors and was acquired by Broadcom Corp. in 2010. Paulraj received the IEEE Alexander Graham Bell award given to pioneers of mass impact telecom technologies. He is a member of the US National Academy of Engineering, the Royal Swedish Academy of Engineering Sciences among others. Paulraj spent about 20 years in India building sonar systems and founded several labs for which he received the Padma Bhushan award.
