Notes/Equations
- This model is used to generate PCPCH preamble. Each preamble is 4096 chips.
- The preamble code is a complex-valued sequence built from a preamble scrambling code and a preamble signature as defined in [2].
This model can simulate Access Preamble (resources shared with PRACH or not) and Collision-Detection Preamble. - This model outputs one token each firing. After 4096 firings, it outputs 0.
