Notes/Equations
  1. This model is used to implement second interleaving, which is a block interleaver with inter-column permutations. Refer to [1].
  2. This model fires once per radio frame. Each firing, this model receives data blocks of all physical channels at DataIn, then interleaves the data blocks of each physical channel.
