MATLAB Simulation of GSM System

This project presents a comprehensive MATLAB simulation of a GSM (Global System for Mobile Communications) system. The simulation implements a complete signal processing chain where information undergoes multiple stages: outer encoding (typically using cyclic redundancy check or similar error detection codes), inner encoding (commonly convolutional coding for error correction), followed by data rearrangement and bit interleaving to combat channel fading effects. The processed signal then passes through a simulated communication channel model that introduces realistic impairments. At the receiver side, the simulation performs corresponding decoding operations including deinterleaving and iterative decoding algorithms to recover the original information. The implementation includes performance estimation metrics such as bit error rate (BER) calculations and frame error rate analysis through Monte Carlo simulations. This simulation provides valuable insights into GSM system operation principles, signal processing techniques, and communication performance characteristics under various channel conditions. Key MATLAB functions employed likely include communication toolbox components for channel coding, interleaving, and modulation/demodulation operations.
