Dinesh Bharadia, a graduate of Indian Institute of Technology (IIT) Kanpur, was honoured with the 2016 Marconi Society Paul Baran Young Scholar Award that carries a cash prize of USD 4,000.
Bharadia’s research disproved a long-held assumption that it is “generally not possible for a radio to receive and transmit on the same frequency band because of the interference that results.”
His work culminated in making full-duplex radios a reality through the development of effective self-interference cancellation technology.
Bharadia, who pursued his PhD from Stanford University in the US, will receive the award in November in California.
Problem he solved
Let’s say you are shouting at someone and they are shouting at you. 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.
