MATLAB Implementation of DPSK with BER Analysis

This MATLAB implementation of Differential Phase Shift Keying (DPSK) includes complete BER (Bit Error Rate) plotting functionality. The program enables users to thoroughly analyze and research the performance characteristics of DPSK signals through systematic simulation. The implementation features key MATLAB functions for: - DPSK modulation using phase difference encoding between consecutive symbols - AWGN channel simulation with configurable signal-to-noise ratio (SNR) parameters - Differential demodulation process with phase comparison techniques - BER calculation through bit-by-bit comparison between transmitted and received data - Graphical BER performance plotting using semilogarithmic scales for clear visualization The code structure includes modular components for signal generation, modulation/demodulation processing, error counting, and result visualization, making it suitable for both educational purposes and practical communication system analysis.
