This talk will overview how transmit power can be allocated across multiple transmit antennas in MIMO systems. While most results for MIMO transmission assume sum power constraint, a per antenna power constraint is more likely in practice with one PA feeding each antenna. Also EIRP constraints may have to be enforced. In many cases, the channels associated with the antennas are imbalanced, which can make the one PA per antenna design lossy. Use of Power Combining Networks can improve performance significantly. This overview talk studies this problem and describes solutions using power combining networks.

Biography: Arogyaswami Paulraj is a Professor Emeritus at Stanford University. Paulraj has received several awards in the US, notably the IEEE Alexander Graham Bell Medal. He is a fellow of seven scientific academies including the US National Academy of Engineering and the Royal Swedish Academy of Engineering Sciences. He is a fellow of IEEE and AAAS . In 1999, Paulraj founded Iospan Wireless Inc – which developed the first MIMO -OFDMA wireless system. Iospan was acquired in by Intel Corporation in 2003. He was in 2004, Paulraj co-founded Beceem Communications Inc and the company was acquired by Broadcom Corp. in 2010. During his 30 years in the India, he founded three national level laboratories and headed one of India’s most successful defense R&D projects – APSOH sonar. His many awards in India include the Padma Bhushan, the third highest national award.
