C-DOT & IIT Mandi to Develop Wideband Spectrum Sensor Chip

The Centre for Development of Telematics (C-DOT), in collaboration with IIT Mandi and IIT Jammu, has taken a significant step in developing state-of-the-art telecommunications technology by signing an agreement for the development of a Wideband Spectrum-Sensor ASIC-Chip. This project is aimed at enhancing spectrum utilization, ensuring efficient broadband services, particularly in rural India. It falls under the Telecom Technology Development Fund (TTDF) scheme, supporting India’s vision of Atmanirbhar Bharat and Make-in-India.

Key Highlights

Project and Goals

• Development of Wideband Spectrum-Sensor ASIC-Chip to improve spectrum efficiency.
• Focus on designing hardware-friendly communication algorithms for wideband spectrum sensing.
• Target spectrum beyond 2 GHz bandwidth to utilize under-utilized bands or white spaces.
• Aim to enhance broadband access in rural India by leveraging spectrum holes.

Technological Innovations

• Spectrum sensing enables Cognitive Radio to adapt to the environment without interfering with the primary network.
• Development of efficient hardware architectures for,
• Short sensing time
• High data throughput
• Enhanced hardware efficiency
• Initial emulation of designs in the FPGA environment followed by ASIC semiconductor-chip development.
• Demonstration of a wideband cognitive radio module for the 6 GHz satellite band (5.925–7.125 GHz).

Key Benefits

• Boosts throughput of cognitive radio networks.
• Enhances spectrum utilization efficiency for communication systems.
• Creates intellectual properties (IPs) for dynamic spectrum access technology.
