Notes/Equations
  1. 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].
  2. 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.
  3. 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".
