Beyond 5G: SDSU Professor Earns NSF CAREER Award | NewsCenter | SDSU - SDSU Newscenter

We person sensors successful our cars, our phones, and present adjacent our homes — each meant to marque our day-to-day lives easier done the usage of wireless communications. Electrical and Computer Engineering prof Duy Nguyen wants to marque these instrumentality learning and awesome processing algorithms adjacent stronger — and our lives adjacent easier.

Nguyen has earned an NSF CAREER Award of $500,000 implicit the adjacent 5 years for his probe connected wireless communications, awesome processing, and instrumentality learning. The NSF Faculty Early Career Development (CAREER) Award is the NSF’s astir prestigious grant for early-career faculty.

More Antennas, More Data

Nguyen’s enactment deals with MIMO(multiple-input, multiple-output) systems, a wireless exertion that uses aggregate transmitter and receiver antennas to transportation much information astatine the aforesaid clip to thing requiring it, specified arsenic a astute watch. 

MIMO came to popularity during the emergence of the wireless section country web (LAN), a wireless machine web that links 2 oregon much devices utilizing wireless connection to signifier a LAN wrong a constricted area, similar an bureau building. This enabled the on-the-go net usage of users connected laptops and compartment phones. 

MIMO exertion yet led to 3, 4, and present 5G information networks. "With MIMO, you tin transmit aggregate information streams astatine the aforesaid clip and connected the aforesaid frequency," said Nguyen. "By expanding the fig of antennas, you tin greatly summation the information rates. That's a cardinal exertion for 5G reception."

More Wi-Fi antennas successful your home, for instance, let for much devices specified arsenic phones, televisions, and computers to link astatine erstwhile with beardown reception. The aforesaid conception applies to information connectivity successful mundane life, said Nguyen. 

"We request monolithic connectivity successful the future. Cars, cameras, and different devices person a batch of sensors, and the lone mode to enactment galore devices is to summation the magnitude of the data," said Nguyen.

The request for enabling monolithic connectivity utilizing energy- and cost-efficient monolithic MIMO wireless transceivers, mobile devices, sensors, and actuators motivates the usage of low-cost hardware. However, these hardware components are highly susceptible to generating nonlinear distortions.

Nguyen, who is celebrating his seventh twelvemonth arsenic a prof astatine SDSU, receives the 2022 NSF CAREER grant to make caller learning frameworks and awesome processing algorithms to resoluteness the nonlinearities successful wireless transceivers and optimize monolithic MIMO performance. He volition start, helium said, with a applicable exemplary that volition past make into an algorithm connected apical of the model.

Optimizing Future Telecommunications

On apical of this, Nguyen has besides earned different collaborative NSF grant that volition absorption specifically connected 5G networks, which helium volition enactment connected alongside collaborators astatine the University of California, Irvine.

"I person been truthful fortunate to person had Duy arsenic a collaborator,” said Lee Swindlehurst, prof of Electrical Engineering and Nicolaos G. and Sue Curtis Alexopoulos Presidential Chair astatine UC Irvine. “He has brought truthful galore caller ideas and perspectives to maine and my probe group. He is arsenic beardown a young prof arsenic determination is successful the U.S. close present moving connected problems successful awesome processing for wireless communications.”

Nguyen's Ph.D. students person besides expressed their appreciation for the skills learned successful Nguyen's laboratory: “I person learned truthful overmuch from Dr. Nguyen’s singular method cognition and probe enthusiasm, and I americium truthful blessed that his untiring probe efforts and patience person been recognized with these caller NSF grants”, said Van Ly, a Ph.D. pupil moving nether Nguyen for 5 years.

To assistance with these 2 probe grants, Nguyen looks guardant to recruiting  2 to 3 caller Ph.D. students for autumn 2023 to absorption connected wireless communications, awesome processing, and instrumentality learning.

As for coursework, Nguyen plans to usage his probe backing to make a integer communications people — 1 successful which helium is capable to incorporated hardware. Currently, the people lone has the capableness to absorption connected theory, but with the assistance helium hopes to incorporated off-the-shelf hardware to make wireless communications systems of their own. 

Nguyen is disconnected to the races. He says astatine the complaint helium and different researchers are going, adjacent faster and much data-heavy 6G networks should beryllium disposable to america connected our phones successful little than 10 years.
