MATLAB Simulation of Power Spectrum Analysis

This resource provides MATLAB simulation code for power spectrum analysis, designed to support your research and learning endeavors. Power spectrum is a fundamental concept in signal processing that characterizes the frequency distribution of signal power. In modern communication and radar systems, power spectrum analysis serves as an indispensable tool for signal characterization. The included code demonstrates practical implementation using MATLAB's signal processing functions, including periodogram estimation and Welch's method for reduced variance. You can modify parameters such as window functions, FFT length, and overlap segments to adapt the analysis to various application scenarios. The code structure emphasizes clarity with commented sections explaining key algorithmic steps, including data preprocessing, Fourier transformation, and spectral normalization. We encourage you to customize these examples for your specific needs and share this resource with others in the technical community.
