Notes/Equations
  1. This model is used for uplink DPCCH simulation. This model performs the same as the Agilent signal generator instrument ESG-D Option 100.
  2. Each firing, 2560 tokens are output. The complex output data sequence is the spread and scrambled chips where SpreadCode and ScrambleCode specify the spread and scramble codes. The output sequence is repeated on a frame-by-frame basis.
  3. The combined parameters, such as number of FBI bits, TFCI field switch are converted to the slot format as defined in [1].
  4. Hexadecimal TPC values are converted to their binary equivalent. For example, if the TPCValue is set to 0 x 7F80, it becomes 111 1111 1000 0000. Note that there are 15 digits in the binary TPC value. Because one frame contains 15 time slots, one binary digit is assigned to each time slot (see the following table). The assigned bit is then repeated to fill the TPC bit field. Since the example in the following table uses two TPC bits per time slot, the values are either 11 or 00.

    TPC Bits per Time Slot
  5. The FBI values are converted into a binary equivalent and filled in each slot.
  6. If TFCIField is on, the TFCI value is converted into a 10-bit binary equivalent and coded to 32 bits, then filled in the TFCI field of each slot.
  7. DPCCH is always channelized on Q branch.
