Zeng Receives NSF award

Dr. Huacheng Zeng, Assistant Professor of Computer Science and Engineering, has been awarded an NSF grant in the amount of $400,000. The project title is “Collaborative Research: Breaking Information Sharing Barrier at Signal Level: A Learning-based Interference Mitigation for Pay-As-You-Go Spectrum Sharing.”

Abstract:

The growing stress from spectrum shortages and the increasing demand for wireless applications are propelling spectrum management into its fourth era. The "Pay-As-You-Go and Cooperative Sharing" vision is poised to be a promising new paradigm for spectrum management in Spectrum Era 4. In this vision, despite cooperation among wireless users, the information they can share is limited to system/protocol-level parameters (e.g., spectrum requirements, interference tolerance levels, wireless standards, and waveform types). However, signal-level information, representing instantaneous transmission details of individual data packets (e.g., channel coefficients), cannot be shared in a timely manner across different wireless networks due to delays in cross-network information exchange. This project aims to fill this critical gap by investigating interference mitigation techniques for wireless devices in the absence of signal-level interference information. The research team will design learning-based approaches for individual radio devices to decode their data packets in the presence of unknown interference. The team will also integrate the proposed interference mitigation algorithms into 5G Open Radio Access Networks (O-RANs) and evaluate their performance in realistic scenarios through comprehensive experimentation. Moreover, the project will promote the participation of women and students from underrepresented groups in wireless communications research. It will also enhance pedagogical activities by developing new course materials based on the research findings.
