Full duplex radio

Indian techie does with radio what Marconi couldn't Sep 15 2016 : The Times of India (Delhi)

For his PhD at Stanford, 28-year-old electrical engineer Dinesh Bharadia decided he was not going to choose a problem that was “trivial“. So he settled in on something that had stumped scientists for 150 years -how to turn radio communication two-way .

And he did it in just a couple of years, by creating a `full duplex radio'. For this, Bharadia, a researcher at Massachusetts Institute of Technology (MIT) who grew up in Kolhapur, has been awarded the prestigious 2016 Marconi Society Paul Baran Young Scholar Award, which he will receive at a ceremony at the Computer History Museum in California on November 2.

The award is named after Guglielmo Marconi, the inventor of radio, known for his work on long-distance radio transmission. Ironically , Marconi couldn't solve the problem of duplexing.

In a telephonic interview to TOI from his home in Cambridge, Masachusetts, Bharadia said what he had designed was self-interference cancellation technology , which means it would now be possible for a radio to receive and transmit on one frequency band.

Meanwhile, another IndoAmerican scientist from MIT, Nashik-born Ramesh Raskar, has been conferred with the $500,000 Lemelson-MIT Prize 2016, it was announced at Cambridge, Massachusetts, on Tuesday . Raskar is the coinventor of radical imaging solutions including femtophotography -an ultra-fast imaging system that can see around corners -low-cost eye-care solutions for the developing world, and a camera that allows users to read a book without opening the cover.
