Notes/Equations
  1. This model is used to generate PRACH preamble. The PRACH preamble consists of 4096 chips.
  2. The preamble code is a complex-valued sequence built from a preamble scrambling code and a preamble signature as defined in [2].
  3. Each firing, one token is output. After 4096 firings, 0 is output.
