Notes/Equations
- This model is used to insert pilot symbols into the STTD encoded sequence for downlink DPCHs.
Each firing, Slot_L tokens are produced at out1 and out2 when DPCH_L tokens are consumed at DPCH1 and DPCH2. Token values are given in the following table.- For SF = 256 DPCH, if there is only one dedicated pilot symbol, it is encoded with the last symbol (data or DTX) of the second data field. This model then completes STTD encoding and insertion of this single pilot symbol.
