Notes/Equations
- 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.
- Binary input bits are mapped to real values according to the mapping rule and then multiplied one-by-one by inData with inSeq.
