The concept of cognitive radio is to exploit the underutilized spectral resources by reusing unused spectrum in an opportunistic manner. A cognitive radio system generally involves primary users of the spectrum, who are incumbent licensees, and secondary users who seek to opportunistically use the spectrum when the primary users are idle. The cognitive radios must sense the spectrum to detect whether it is available or not. We derive, implement and evaluate the energy detector and the cyclostationary detector. We evaluate the performance of the detectors by plotting the Receiver Operating Characteristics (ROC) under clean and noisy conditions. ### Built With This project was built with * python v3.7 * The list of libraries used for developing this project is available at [requirements.txt](requirements.txt). <!-- GETTING STARTED --> ## Getting Started Clone the repository into a local machine using ```shell git clone https://github.com/vineeths96/Spectrum-sensing-for-cognitive-radio ``` ### Prerequisites Please install required libraries by running the following command (preferably within a virtual environment). ```shell pip install -r requirements.txt ``` ### Instructions to run The `energy_detector.py` acts as an interface to the Energy detector implementations in `energy_detector` package. The `cyclostationary_detector.py` acts as an interface to the Cyclostationary detector implementations in `cyclostationary_detector` package. The python files take care of the generating the test statistics, implementation of hypothesis testing and the plotting of the results. The respective program can be executed by ```shell python <file_name>.py ``` <!-- LICENSE --> ## License Distributed under the MIT License.
