The Centre for Development of Telematics (C-DoT), the premiere telecom research and development center, under the government of India signs an MoU with the Indian Institute of Technology Mandi (IIT Mandi) in collaboration with Indian Institute of Technology Jammu (IIT Jammu), for the development of "Wideband Spectrum-Sensor ASIC-Chip for Enhancing the Spectrum Utilization".

The funds have been granted under the Telecom Technology Development Fund (TTDF) scheme of the Department of Telecommunications, Government of India. 

Objective 

The project has been funded to develop a reliable and implementation-friendly wideband spectrum sensing (WSS) algorithm to improve spectrum efficiency by leveraging spectrum holes to deliver broadband services in rural India, the press release stated. 

Spectrum sensing enables cognitive Radio users to adapt to the environment by detecting spectrum holes without causing interference to the primary network.

Project scope 

This project aims to design specific kinds of communication algorithms that are hardware-friendly for sensing the wideband spectrum (beyond 2 GHz of bandwidth) for detecting and utilizing the under-utilized bands (or white spaces), thus, enhancing the spectrum utilization efficiency of any communication system. In addition, efficient hardware architectures of such spectrum sensors will be developed in this project that achieve short sensing time, high data throughput, and enhanced hardware efficiency.

Utility 

The initiative will provide a hardware solution capable of scanning over 2 GHz of spectrum with minimal sensing time, thereby boosting the throughput of cognitive radio networks. Additionally, it will demonstrate a wideband cognitive radio module targeting the 6 GHz satellite band (5.925–7.125 GHz) for spectrum sensing and communication. The project will also lead to the creation of intellectual properties (IPs) for the wideband spectrum sensing technology which is the key component for the dynamic spectrum access.

Technological advancement 

At the event, Dr. Shrestha and Dr. Chaurasiya affirmed their dedication to advancing the technology of dynamic spectrum access via the development of novel algorithms as well as hardware modules for wideband spectrum sensing which are in line with the objectives of Make-In-India and India-Semiconductor Missions of Government of India.
