Turbo Code Encoding and Decoding Simulation

This document explores the implementation of Turbo code encoding and decoding through MATLAB simulation using an M-file. The simulation file incorporates several critical components including the encoding algorithm (typically using parallel concatenated convolutional codes), decoding algorithms (employing the iterative MAP or Log-MAP algorithm), and appropriate data structures for efficient processing. Key implementation aspects involve setting up the interleaver pattern, configuring the constituent encoders, and implementing the iterative decoding process with stopping criteria. The simulation also addresses performance evaluation metrics such as bit error rate (BER) analysis under different signal-to-noise ratio conditions. When developing this M-file, careful attention must be paid to algorithmic details, memory allocation, and computational efficiency to ensure accurate and reliable results. The simulation output enables comprehensive analysis of Turbo code performance characteristics, including convergence behavior and error correction capabilities.
