64-QAM (Quadrature Amplitude Modulation) Implementation

I have developed a MATLAB program implementing 64-QAM (Quadrature Amplitude Modulation) that is fully executable and generates comprehensive graphical outputs. This robust program employs key digital communication techniques including constellation mapping, IQ modulation, and pulse shaping to create an efficient signal transmission system. The implementation features a 64-point constellation diagram with Gray coding optimization to minimize bit error rates, along with MATLAB's communication toolbox functions for signal processing and visualization. The program demonstrates practical applications in communication systems by generating modulated waveforms, displaying eye diagrams, and plotting error performance curves. It includes functionality for simulating transmission channels and analyzing system performance through BER (Bit Error Rate) calculations. The code structure allows for easy parameter modification, making it suitable for both educational purposes and professional communication system design. This implementation provides clear visual representations of modulated signals, spectrum analyis, and demodulation results, making complex modulation concepts accessible to users at all skill levels. Whether for academic research or engineering applications, this program offers significant advantages in understanding and implementing digital modulation schemes.
