Notes/Equations

This 3GPPFDD_HS_UL_Rake model receiver provides HS-DPCCH de-spreading and de-modulation.
3GPPFDD_UL_Rake (dedicated physical channel uplink receiver) functions are implemented in this receiver. Refer to 3GPPFDD_UL_Rake documentation for parameter information and details.
The HS-DPCCH is de-spread and de-modulated after DPCCH and DPDCH signals are processed.
The envelope ratio between HS-DPCCH and DPCCH is calculated for each slot.
