Course design implementing two programs: 1) Turbo code encoding and decoding for 400-bit data frames transmitted over noisy channels, simulating Log-MAP decoding algorithm performance across different iteration counts. 2) Performance evaluation of Turbo codes using MAP decoding algorithm under varying signal-to-noise ratios in noisy channels. Both main programs include comprehensive code comments and can be executed directly via turbo_main.m or LogMAP.m to observe simulation results within moments.

Traditional convolutional codes and Turbo codes remain widely used today, but both exhibit a significant drawback in information transmission. To address this limitation, the IEEE 802.16d/e standard introduced the Convolutional Turbo Code (CTC) encoding scheme. This MATLAB code implements complete CTC encoding and decoding processes, incorporating key algorithmic components like parallel concatenated convolutional encoders and iterative MAP decoding. The implementation demonstrates valuable insights into enhancing data transmission efficiency and reliability through turbo-principle-based error correction.
