Notes/Equations
- This subnetwork model is used to perform channel decoding.
- When LinkDir is set to DownLink and TrCHType is set to DCH_8_kbps, no coding is decoded.
- When LinkDir is set to UpLink and TrCHType is set to DCH_8kbps, convolutional coding is decoded.
- When TrCHType is set to DCH_16_kbps, DCH_32_kbps, DMCH_2_4_kbps, DMCH_12_2_kbps, BCH_11_1_kbps or BCH_12_3_kbps, convolutional coding is decoded.
- When TrCHType is set to DCH_64_kbps, DCH_128_kbps, DCH_256_kbps, DCH_512_kbps, DMCH_64_kbps, DMCH_144_kbps, DMCH_384_kbps, turbo coding is decoded.
The schematic for this subnetwork is shown in the following figure.
