About WCRL
The Wireless Communication Research Lab (WCRL) at IIT Patna, led by Prof. Preetam Kumar in the Department of Electrical Engineering, is committed to advancing the field of next-generation wireless communication systems through both theoretical and experimental research. The lab primarily focuses on addressing open challenges at the physical layer, aiming to enhance communication efficiency, reliability, and adaptability in complex and dynamic wireless environments.
WCRL’s research covers a broad range of modern technologies, including Reconfigurable Intelligent Surface (RIS)-assisted communication, Index Modulation (IM), Orthogonal Frequency Division Multiplexing (OFDM), and Integrated Sensing and Communication (ISAC). In addition to conventional signal processing techniques, the lab also integrates Artificial Intelligence (AI) and Machine Learning (ML) methods into wireless system design and optimization. These data-driven approaches are applied for tasks such as channel estimation, resource allocation, beamforming, and network adaptation, enabling intelligent and adaptive communication frameworks. The research workflow at WCRL typically begins with mathematical modeling and analytical validation, followed by simulation-based evaluation using statistical and AI/ML-based system models. Once the theoretical models are verified, the team transitions to hardware implementation using platforms like the NI-PXI (National Instruments PXIe) machine for real-time testing and prototyping.
WCRL is actively engaged in several government-sponsored projects and industry collaborations, focusing on technology development and transfer to practical applications. The lab has also filed multiple patents and consistently publishes high-quality research in leading journals and conferences. Through its interdisciplinary work combining signal processing, wireless communication, and AI-driven design, WCRL continues to play a vital role in shaping the future of intelligent and energy-efficient communication systems.
