MATLAB Programming for 2PSK Modulation Process

This MATLAB-based program implements 2PSK (Binary Phase Shift Keying) modulation programming, generates simulated waveforms, and performs power spectral analysis. The program allows users to input key parameters such as carrier frequency, modulation index, and signal duration to simulate the complete 2PSK signal transmission process. The implementation typically involves generating random binary data using functions like randi(), modulating the carrier wave by shifting phase by 180 degrees for binary 1 and 0 degrees for binary 0, and adding AWGN (Additive White Gaussian Noise) using awgn() function to simulate realistic channel conditions. The simulation waveforms clearly display both modulation and demodulation processes, including noise effects on signal integrity. For power spectrum analysis, the program employs FFT (Fast Fourier Transform) algorithms through functions like pwelch() or periodogram() to analyze spectral characteristics. This analysis reveals critical frequency-domain properties including main lobe width, signal bandwidth, and power distribution patterns. The power spectral density plot helps identify signal concentration in frequency domain and potential interference aspects. Through this comprehensive MATLAB implementation, users can gain deeper understanding of 2PSK modulation principles and perform sophisticated signal analysis and processing tasks. The code structure typically includes separate modules for signal generation, modulation, channel simulation, demodulation, and analysis, providing a complete educational framework for digital communication systems.
