Saswati Paramita has developed expertise in Li-Fi networks, with a particular focus on the physical and MAC layers of communication. Her research explores the limitations of indoor Li-Fi systems and addresses the growing challenge of RF spectrum scarcity. She has extensively worked on hybrid Li-Fi/Wi-Fi networks, identifying key research gaps and proposing efficient resource allocation algorithms and link aggregation techniques to optimize the performance of both Li-Fi and Wi-Fi links.
She has contributed significantly to a funded project by the Ministry of Electronics and Information Technology (MeitY), Government of India, where she helped develop a prototype testbed for hybrid Li-Fi/Wi-Fi networks. Her research findings have been published in prestigious IEEE journals and international conferences, where she has also demonstrated her testbed solutions. Notably, her work has been showcased at India Mobile Congress (IMC) and the ITU-World Telecommunication Standardization Assembly (ITU-WTSA).
Saswati received the Award of Excellence in Research and Innovation from IIIT-Delhi, recognizing her impactful contributions. She has also mentored numerous interns across institutions on Li-Fi/Wi-Fi projects and served as a teaching assistant for courses such as Wireless Networks, Circuit Theory and Design, Wireless System Implementation, and Research Methods. She has successfully completed advanced coursework at IIIT-Delhi in areas including Optical Wireless Communication, Probability Theory and Random Processes, and Wireless Networking.

Thesis Title: Synchronization in OFDM System
Description: Orthogonal frequency division multiplexing (OFDM) is one of the multicarrier modulation techniques, which transmits data in very high rate and efficiently mitigates the effects of multipath distortions as well as loss in bandwidth efficiency. However, OFDM systems are very sensitive towards synchronization error. Synchronization of an OFDM signal requires finding the symbol timing and carrier frequency offset (CFO). Before demodulation of subcarriers, either from explicit training data or using cyclic prefix of the OFDM signal we can get synchronization at receiver. After demodulation of the subcarriers, the synchronization information can be obtained from training symbols embedded into the regular data symbol pattern. The estimation of synchronization error can be performed depending on the type of the training data. In this project, it is focused on preamble based training data following IEEE802.11a preamble structure of the WLAN system and cyclic prefix based training data.
