Notes/Equations
  1. This subnetwork model measures code domain error. The error vector obtained during EVM calculation is then used to measure code domain error.
  2. 3GPPFDD_CodeDomainErr_NonSyn uses the same EVM measurement method as 3GPPFDD_EVM. This method is sensitive to the synchronization performance.
    3GPPFDD_CodeDomainErr_NonSyn uses the same error vector method as 3GPPFDD_EVM_NonSyn. The same robustness is achieved by using the same exhaustive offset search as in 3GPPFDD_EVM_NonSyn.
    Refer to 3GPPFDD_CodeDomainErr, 3GPPFDD_EVM and 3GPPFDD_EVM_NonSyn for information regarding EVM and code domain error measurement.
  3. The 3GPP system chip rate is 3.84 Mcps. The BS_Tx_Pk_Code_Error.dsn design demonstrates the use of this subnetwork model in the Examples WCDMA3G/WCDMA3G_BS_Tx_prj; this project is discussed in Base Station Transmitter Design Examples.
