Implementation of 4QAM Modulation

This repository contains two programs that both implement 4QAM modulation. The first program demonstrates a well-structured approach to 4QAM implementation with clear signal mapping, while the second version introduces OFDM techniques with null subcarriers for improved bit error rate performance. Both implementations include MATLAB code examples for digital modulation and demodulation processes.
