ISAC-Sim

Turbo Code

Concatenated code approaching Shannon limit, 3G standard

Real-World Applications

3G (WCDMA/CDMA2000), 4G LTE data channels. Turbo codes approach the Shannon limit, the cornerstone technology of the modern mobile internet explosion.

Experiment Steps

  1. Iteration Gain: Performance improves with each iteration
  2. Waterfall Region: Sharp degradation below SNR threshold
