Notes/Equations
- This model is the flexible orthogonal channel noise simulator.
- Each firing, this model outputs a slot of complex chips that consists of 2560 spread and scrambled complex data bits.
- 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.
- The default OCNS model has 16 dedicated channels with channelization codes, timing offsets and level settings as specified in [4] for test model 1.
- 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
