MATLAB Program for Cognitive Radio Energy Detection and Spectrum Sensing

This MATLAB program is designed for cognitive radio energy detection and spectrum sensing tasks. The implementation utilizes MATLAB's signal processing toolbox to perform real-time monitoring of radio signal energy levels and conduct comprehensive spectrum analysis. The program employs energy detection algorithms that calculate signal power thresholds and compare them against noise floors to identify available spectrum opportunities. Key functions include signal acquisition, Fast Fourier Transform (FFT) processing for frequency domain conversion, and adaptive threshold calculation for dynamic spectrum sensing. The flexible architecture allows users to configure parameters such as detection thresholds, sampling rates, and observation windows according to specific requirements. With an intuitive graphical user interface (GUI) and modular code structure, the program provides visualization of spectrum occupancy and generates detailed analysis reports. This MATLAB implementation serves as a powerful tool for cognitive radio applications, enabling efficient spectrum utilization in various wireless communication scenarios through configurable detection parameters and real-time performance metrics.
