Notes/Equations
  1. This subnetwork is used to provide the signal source for reference measurement channel 2048 kbps [1] for the user equipment in an uplink.
    The schematic for this subnetwork is shown in the following figure. It includes the data source for measurement transport channel, channel coding, transport channel multiplexing, physical channel mapping, spreading and scrambling for dedicated data channel (DPCH).
    This subnetwork outputs the combined complex symbols from out in chips, and outputs TFMax once every 10 msec. The reference data source is output from Ref_DataSrc1/Ref_DataSrc2 every transport block according to the TTI setting of each transport channel. The results for channel coding are output from CoderOutput1/ CoderOutput2 for measurement of BER (bit error rate) before channel coding in coding frames or blocks.
