Notes/Equations
  1. This model is the flexible orthogonal channel noise simulator.
  2. Each firing, this model outputs a slot of complex chips that consists of 2560 spread and scrambled complex data bits.
  3. The number of dedicated channels can be set flexibly from 1 to 512. The dedicated channels of the OCNS signal should be evenly distributed in the code domain; timing offset should be equidistantly distributed over the dedicated channels; level settings of dedicated channels should be similar.
  4. The default OCNS model has 16 dedicated channels with channelization codes, timing offsets and level settings as specified in [4] for test model 1.
  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
