Notes/Equations
- 3GPPFDD_HS_ULSpread provides spreading and scrambling functions for HS_DPCCH as well as DPCCH and DPDCH(s).
Each firing, 2560 out tokens are produced when 10 CtrlIn, one GainD, one GainC, one PCNin, one SltFin, 10 HS_DPCCH, one HS_Gain, and 640 DataIn tokens are consumed. - 3GPPFDD_ULSpread (uplink DPDCH/DPCCH(s) spreading and scrambling) functions are implemented in this model. Refer to 3GPPFDD_ULSpread documentation for parameter information and details.
- The HS-DPCCH is spread and modulated after DPCCH and DPDCH signals are processed. The HS-DPCCH spreading and modulation scheme is defined in [3].
The HS-DPCCH is scaled by the HS-DPCCH gain (the product of gain for DPCCH (GainC) and the gain of HS_DPCCH over DPCCH (HS_Gain) ). If the HS_Gain input is 0, then no HS_DPCCH is transmitted (DTX is transmitted in HS_DPCCH).
