Notes/Equations
- This subnetwork model is used to perform downlink transport channel decoding.
The schematic for this subnetwork is shown in the following figure. It includes radio frame delay, rate dematching, radio frame desegmentation, first de-interleaving, radio frame de-equalization, channel decoding, code block concatenation, and CRC checking.
This subnetwork model performs the inverse function of the WCDMA3G_UnLkTrCHCoding subnetwork model.
