5. Optimization of convolutional turbocodes

Convolutional turbocodes: the turbocode described in the original article achieves correction performance close to theoretical limits. However, as the noise level decreases, its efficiency diminishes. This leads to a so-called floor phenomenon (see figure 21 ): as the noise level falls, the residual error rate continues to decrease, but...
