Detailed Generation and Modulation of 2DPSK using MATLAB

In the following sections, I will provide detailed information about MATLAB implementation for 2DPSK signal generation and modulation. The program includes fully executable code to help you better understand and apply this concept. Specifically, we will cover the complete workflow of 2DPSK signal generation, including bit sequence generation using random number functions, symbol mapping through differential encoding techniques, and carrier modulation using trigonometric functions for phase shifting. The implementation demonstrates key MATLAB functions such as randi() for random bit generation, diff() or custom differential encoding for phase transitions, and cos()/sin() functions for carrier modulation. Additionally, we will discuss performance evaluation metrics including signal-to-noise ratio (SNR) implementation using awgn() function and bit error rate (BER) calculation through comparison algorithms. The code includes proper visualization techniques using plot() and stem() functions for signal analysis. These implementations will help assess 2DPSK performance under various application scenarios.
