Modulation Scheme BER Analysis

This project analyzes the Bit Error Rate (BER) for different modulation schemes (BPSK, QPSK, 16-QAM, and 64-QAM) in MATLAB. It demonstrates the impact of Signal-to-Noise Ratio (SNR) on the performance of each modulation scheme without the use of error-correcting codes.

Key Features:

• BPSK, QPSK, 16-QAM, and 64-QAM modulation schemes.
• Additive White Gaussian Noise (AWGN) is used for simulating noisy channels.
• BER is calculated and plotted against SNR for each modulation scheme.

MATLAB Code:

• modulation_scheme.m: Main script for BER analysis and plotting results.

How to Run:

1. Download or clone the repository.
2. Open the MATLAB script modulation_scheme.m.
3. Run the script to generate BER vs. SNR plots for each modulation scheme.

Requirements:

• MATLAB (R2020 or later recommended)
• Communications System Toolbox

Results:

The script produces a plot showing the BER for different modulation schemes against varying SNR values.
