Notes/Equations
  1. This subnetwork is used to provide the signal source for variable-rate sources ranging from 8 to 512 kbps of the user equipment in an uplink.
    The schematic for this subnetwork is shown in the following figure. It includes the variable-rate data source for transport channel, channel coding, transport channel multiplexing, physical channel mapping, spreading and scrambling for dedicated physical channel (DPCH).
    This subnetwork outputs the combined complex symbols from Out and outputs TFMax once every 10 msec. The reference data source are output from Ref_DataSrc every transport block according to the TTI setting of each transport channel. The results for channel coding are output from CoderOutput for measurement of BER (bit error rate) before channel coding in coding frames or blocks. The DPDCH (dedicated physical data channel) data bits are output from DPCHData for physical channel BER measurement in radio frames (15 slots).
