Improving The Performance Of Spectrum Sensing and Spectrum Allocation Using Non-Cooperative Energy Detection Method

Ramchander Jatooth, T. Srinivasulu


The radio spectrum is limited resource and is regulated by government agencies such as Telecom Regulation Authority of India (TRAI) in India, Federal Communication Commission (FCC) in the United States. Cognitive radio is a novel technology which improves the spectrum utilization by allowing secondary user to borrow unused radio spectrum from primary licensed users or to share the spectrum with the primary users. Here, we are going to implement Software Defined Radio(SDR) with Raspberry which enables transmission signals with the help of general purpose Input-output pins and with help of software. Here the spectrum sensing using the Non-Cooperative Energy Detection method and the signal transmission in the unused spectrum is done . We can establish a FM station with the help of Raspberry Pi based on Cognitive Radio communication and transmission is possible with raspberry which helps to setup our own communication channel with Cognitive frequency.
