Basic Digital Communication System
Using MATLAB simulation software, this project implements a fundamental 16QAM digital communication system as shown in Figure 1. The system generates equally distributed random binary signals (0s and 1s), maps them to 16QAM constellation points, and separates the signal into in-phase (real) and quadrature (imaginary) components. Both components undergo root-raised-cosine (RRC) filtering, experience additive white Gaussian noise (AWGN) channel impairment, and pass through matched RRC filters. The final stage involves sampling, decision-making, and comparison with original signals to calculate the bit error rate (BER) for the 16QAM digital system.
