Notes/Equations
  1. This subnetwork model is used to simulate integrated user equipment signal source. With this subnetwork model, a reference measurement channel signal as defined in 3GPP TS 25.101 can be generated.
    (To view the schematic for this subnetwork, push into the component symbol in the schematic window.)
  2. Designers can set the DPDCH/DPCCH power ratio with this subnetwork. GainUnit is used to specify the method for calculating the DPDCH/DPCCH power ratio. When GainUnit = Index, the gain factors of DPDCH and DPCCH are calculated according to the value of GainIndex. When GainUnit = Value, the gain factors of DPDCH and DPCCH are calculated according to the values of DPDCHGainFactor and DPCCHGainFactor. Note that if reference measurement channels defined in TS 25.101 are required, GainIndex must be set according to the following table.
    GainIndex Value

  3. DPDCHData pin 6 outputs bits of each DPDCH; the width of this multi-pin is controlled by the DPDCHNum parameter in this subnetwork. The real DPDCH number is determined by the rate matching algorithm (maximum is 6); if DPDCHNum is set to a larger value, the additional DPDCH will be filled with 0; if DPDCHNum is set to a smaller value, simulation will not be successful.
    The real DPDCH number may change from 1 to 6 when channel parameters such as block size and block set size are modified. In order for designers to modify those parameters without calculating the real DPDCH number manually, DPDCHNum is set to 6 in this subnetwork.
  4. Pins DCCHCoderOut and DTCHCoderOut output DCCH and DTCH bits after channel coding. Pins DCCH and DTCH output the original DCCH and DTCH bits.
  5. DCCH, DTCH, FBI and TPC data patterns parameters can be modified by the designer.
    Refer to 3GPPFDD_DataPattern regarding setting these parameters.
  6. In uplink, the slot format of DTCH will be determined by rate matching algorithm, while the slot format of DCCH is be given by higher layers. In this model, DPCCH_SltFmt is used to specify the DCCH slot format.
