Using the model in Section 2.1, let us assume that each terminal is assigned only one access port and that each waveform can be used only once by each access port. Let every user be assigned only a single waveform. Finally, when all access ports and/or waveforms are occupied, the remaining users are not assigned any waveforms or ports. What is the number of possible assignments?
