Appendix A

Principal Simulink Blocks used in Chapters 1–13

A.A.1 Sources (Figure A.1)

Notes:

  • The DSP sine wave block is convenient for vector-based computation where that computation method can be selected.
  • The Bernoulli binary generator produces random ones and zeros.
  • The Random integer generator produces M-ary random integers, typically used in conjunction with M-ary modulations.

A.A.2 Sinks (Figure A.2)

Notes:

  • The To Workspace block sends data to the workspace for subsequent study.
  • The display provides a view of the results following the Simulink execution.
  • The scope block enables viewing multiple real-valued waveforms.
  • The Time scope from the DSP library accepts real or complex inputs.
  • The spectrum analyzer has multiple settings including the FFT window size and type.

A.A.3 Modulations (Figure A.3)

Notes:

  • The Communications System Toolbox has an extensive set of digital baseband modulators and demodulators.
  • Many Simulink models developed in this book use BPSK as a well-known modulation, where the focus is typically on another aspect of a complex simulation.
