Notes/Equations
  1. This model is the base station test model 1 as defined in [4].
  2. Each firing, a slot of complex chips is output that consists of 2560 spread and scrambled data.
  3. Test model 1 consists of PCCPCH, SCH, CPICH, PICH, DPCH, and SCCPCH channels (SCCPCH is for Version_03_02 only). Channelization codes, time offset, and power level of each channel are defined in [4].
  4. DPCH channels can be set to 16, 32 or 64.
  5. ScrambleCode i, ScrambleOffset k , and ScrambleType parameters determine the scrambling code n as follows:

    n = (16 ×  i ) + k + m

    • If ScrambleType is normal , m = 0
    • If ScrambleType is right , m = 16384
    • If ScrambleType is left , m = 8192
  6. The DPDCH bits of the DPCHs are filled with PN9 sequences. To ensure non-correlation of the PN9 sequences, each DPDCH uses a unique code Sc as the seed for the PN9 sequence at the start of each frame. The code is determined by the channelization code Cch of the DPCH and a seed offset So as:

    Sc = Cch + So

    The seed offset is set by the Seed parameter to ensure non-correlation of the PN9 sequences when more than one test model is used.
  7. When OutputMode=Ramp, the signal starts from the first frame and channels are added with their time offset; when OutputMode=Stable, the signal is transmitted after all channels are added (the signal starts from the second frame).
