Principal Simulink Blocks used in Chapters 1–13
A.A.1 Sources (Figure A.1)
- 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)
- 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)
- 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.
