Notes/Equations
- This model is used for TFCI combining. The TFCI combination model combine TFIs of TrCHs that are multiplexed into a CCTrCH. The algorithm of TFCI combination is described in [1].
- TFSetSize and TFI are multi-port input. Each TrCH consists of a group of TFSetSize and TFI. TrCHNum determines the number of groups connected to the model.
- The TFSetSizeOut pin outputs TFSetSize serially.
The calculated TFCI cannot exceed 1023.
For example:- TrCH1: TFSetSize = 3, TFI = 2
- TrCH2: TFSetSize = 4, TFI = 3
The TFCI output will be (0 × 3 + 2) × 4 + 3 = 11; the TFSetSizeOut output will be "3 4".
