Resource Overview
This simulation implements energy detection through the main function, where psk_2 handles BPSK modulation, pdsnr calculates theoretical values, and the main function compares theoretical vs. simulation results through graphical plots.
Detailed Documentation
To implement energy detection simulation, the main function performs energy detection operations. For BPSK modulation implementation, the psk_2 function generates binary phase-shift keying signals by mapping binary data to phase shifts of 0 and 180 degrees. The pdsnr function computes theoretical detection performance metrics based on signal-to-noise ratio parameters, implementing statistical models for energy detection thresholds. Finally, within the main function, comparison plots between theoretical values and simulation results are generated using MATLAB's plotting utilities, enabling comprehensive analysis of detection performance under various noise conditions. This approach facilitates detailed evaluation of energy detection algorithm effectiveness through quantitative comparison between empirical simulations and analytical predictions.
