Modulation
The Modulation library contains four sublibraries, each of which addresses a category of modulation:
The main Modulation library appears below. You can open it by double-clicking on its icon in the main Communications Blockset library (commlib), or by typing commmod2 at the MATLAB prompt. Each icon in the Modulation window represents a sublibrary. In Simulink, double-clicking on one of these icons opens the sublibrary.
The first column shows the sublibraries for baseband simulation; the second column shows the sublibraries for passband simulation. The first row shows the sublibraries for digital modulation and demodulation. The second row shows the sublibraries for analog modulation and demodulation.
You can open the Digital Baseband sublibrary of Modulation by double-clicking on the Digital Baseband icon in the main Modulation library, or by typing commdigbbnd2 at the MATLAB prompt.
Digital Baseband is further divided into sublibraries according to specific modulation techniques:
The figures and tables below show and list the blocks in the method-specific sublibraries. For information about a specific block, see the reference pages that follow.
