Generate Simulated BPSK Signals with Spectrum Analysis

In this documentation, we will demonstrate how to generate simulated BPSK (Binary Phase Shift Keying) signals using MATLAB and perform spectral analysis through FFT algorithms. The implementation involves using MATLAB's signal generation functions to create BPSK signals with configurable parameters such as carrier frequency, sampling rate, and data sequence length to simulate desired signal characteristics. For spectral analysis, we employ the FFT algorithm to transform the time-domain BPSK signal into frequency-domain representation, using MATLAB's fft() function with proper windowing and zero-padding techniques to achieve accurate frequency resolution. The analysis reveals key spectral properties including frequency components, power distribution, and bandwidth characteristics of the BPSK signal. This process provides valuable insights into BPSK signal behavior, enabling better understanding of modulation characteristics and facilitating system performance evaluation. The MATLAB implementation includes essential functions like pskmod() for modulation, fft() for transformation, and psd() for power spectral density calculation, with visualization through plotting functions to display both time-domain waveforms and frequency-domain spectra.
