The Centre for Development of Telematics (C-DOT) initiated a transformative project in telecommunications. This project aims to enhance spectrum utilization in India through the development of advanced technologies. The collaboration involves C-DOT, the Indian Institute of Technology Mandi (IIT Mandi), and the Indian Institute of Technology Jammu (IIT Jammu). This initiative is part of the Telecom Technology Development Fund (TTDF) scheme by the Government of India.
Overview of the Project
The project focuses on creating a “Wideband Spectrum-Sensor ASIC-Chip”. This chip will improve spectrum efficiency by detecting under-utilised frequency bands. The goal is to provide better broadband services, especially in rural areas. The development of this technology is crucial for bridging the digital divide in India.
Importance of Spectrum Sensing
Spectrum sensing is a technology that allows cognitive radio users to identify unused frequency bands. This capability enables efficient communication without interfering with existing networks. The project aims to enhance the efficiency of communication systems by utilising these spectrum holes.
Technical Aspects
The project will develop a wideband spectrum sensing (WSS) algorithm. This algorithm is designed to work effectively with hardware, ensuring quick sensing times and high data throughput. The system will scan over 2 GHz of spectrum, improving the performance of cognitive radio networks.
Implementation and Development
The initial designs will be tested using field-programmable gate-array (FPGA) technology. Following successful emulation, an application-specific integrated circuit (ASIC) will be created. This process will lead to the development of a robust hardware solution for spectrum sensing.
Intellectual Property and Future Prospects
The project is expected to generate intellectual properties related to wideband spectrum sensing technology. This technology is vital for dynamic spectrum access, which is crucial for future telecommunications advancements. The collaboration aligns with the Government of India’s initiatives such as Make-In-India and the India-Semiconductor Missions.
Commitment to Indigenous Development
C-DOT’s CEO, Dr. Raj Kumar Upadhyay, emphasised the importance of indigenously developed technologies. He stated that these advancements cater to India’s diverse needs. The project showcases a commitment to “Atmanirbhar Bharat”, promoting self-reliance in the telecommunications sector.
Collaboration and Acknowledgements
The agreement signing ceremony included figures from C-DOT and the collaborating IITs. The Principal Investigator from IIT Mandi, Dr. Rahul Shrestha, and Co-Investigator from IIT Jammu, Dr. Rohit B. Chaurasiya, expressed their enthusiasm for contributing to this essential research. Their dedication aims to enhance research capabilities in the telecommunications sector.
