Error-correction codes in cellular communications: from GSM to 5G — simulating in MATLAB
Summary
This article explains how error-correcting codes evolved across cellular generations from GSM to 5G, then shows how to simulate their bit error rate in MATLAB. It compares basic channel models and walks through practical coding schemes such as Hamming, BCH, convolutional, turbo, and LDPC codes. The piece includes MATLAB snippets for BER testing and demonstrates how coding improves performance under noisy channels. It is primarily an educational engineering article focused on telecom software and signal-processing simulation.
