Notes/Equations
  1. This model is used to complete BPSK data mapping and spread input data. Each firing, SF tokens are produced for each inData and SF inSeq tokens consumed.
  2. Binary input bits are mapped to real values according to the mapping rule and then multiplied one-by-one by inData with inSeq.
