16QAM Modulation and Demodulation Course Project

The Modulation and Demodulation Course Project serves as a fundamental component in communication engineering education, focusing on the design and implementation of 16QAM (16-Quadrature Amplitude Modulation) systems. This project involves developing MATLAB/Python code that implements 16QAM modulation and demodulation algorithms, including key analytical components: constellation diagram visualization using scatter plots, spectrum analysis through FFT-based power spectral density calculations, and bit error rate (BER) performance evaluation under different signal-to-noise ratio conditions. These techniques are critical in modern communication systems as they enable efficient data transmission and reliable signal recovery. Through this course project, students will gain hands-on experience in implementing digital modulation schemes, analyzing system performance using practical coding approaches, and applying communication theory to solve real-world transmission challenges. The project emphasizes code implementation details such as symbol mapping/demapping algorithms, pulse shaping filters, and synchronization techniques, providing comprehensive insights into digital communication system design.
