Dinesh Bharadia, an Electrical Engineering graduate of IIT Kanpur solved a problem that bothered scientists for almost 150 years. Dinesh currently a researcher at MIT, has been honored for the his work with the 2016 Marconi Society Paul Baran Young Scholar Award.
After completing his MS and PhD from Stanford, Dinesh wanted to take up a difficult problem. His pathbreaking research disproved that, it is “generally not possible for a radio to receive and transmit on the same frequency band because of the interference that results.”
He successfully created full-duplex radios through effective self-interference cancellation technology.
“Let’s say you are shouting at someone and they are shouting at you,” Bharadia explained. “Neither of you can hear the other, because you are both shouting in the same frequency. The noise in your ears (“interference”) from your own shout prevents you from hearing the other person. That’s a good analogy for why radios have needed to use two different frequencies to transmit and receive simultaneously. It’s also why solving the challenge of developing ‘full duplex radios’ effectively doubles the amount of available spectrum.”
Bharadia said, “Marconi, invented the radio but couldn’t solve the problem of duplexing, it’s fitting that this work should be recognized by the Marconi Society.”
The Marconi Society was established in 1974 by the daughter of the Nobel Laureate who invented radio, Guglielmo Marconi.
