Stanford University's Professor (Emeritus) Arogyaswami Joseph Paulraj has been awarded the prestigious 2014 Marconi Society Prize for his idea for using multiple antennas at both the transmitting and receiving stations.
His work in MIMO technologies is fundamental to current Wi-Fi and 4G systems.
In 1992, Paul was granted a U.S, patent titled “Distributed Transmit – Directional Receive DTDR” (with his then supervisor Prof. Kailath as co-inventor). Spatial Multiplexing, as this is now known, boosts spectral efficiency by creating “parallel spatial data streams” within the same frequency channel.
The Marconi Society, which is celebrating its 50th year in 2014, has posted Professor Paulraj's story online.
