Several Practical M-DPSK and MPSK BER Analysis MATLAB Programs

This article presents several practical MATLAB programs for analyzing bit error rates in M-DPSK (Multiple Differential Phase Shift Keying) and MPSK (Multiple Phase Shift Keying) modulation schemes. These implementations provide comprehensive BER (Bit Error Rate) performance evaluation across different modulation orders and signal-to-noise ratio conditions. The programs incorporate key functions for signal generation, modulation/demodulation processing, noise simulation, and error counting algorithms to accurately measure transmission performance. Through these simulations, researchers can conduct comparative analysis of various modulation schemes, enabling informed selection of optimal communication strategies based on specific application requirements. The code structure includes modular components for theoretical BER calculation validation and Monte Carlo simulation approaches, making it suitable for both educational purposes in digital communications courses and advanced research in wireless transmission systems. These MATLAB implementations serve as valuable tools for understanding modulation trade-offs between bandwidth efficiency and error performance in practical communication scenarios.
