Digital Passband Modulation

You can open the Digital Passband sublibrary of Modulation by double-clicking on the Digital Passband icon in the main Modulation library, or by typing commdigpbnd2 at the MATLAB prompt. clicking on one of the icons below jumps to an overview of that sublibrary.

Digital Passband is further divided into sublibraries according to specific modulation techniques:

• Amplitude modulation (PAM, QAM)
• Phase modulation (PSK, DPSK)
• Frequency modulation (FSK)
• Continuous phase modulation (MSK, GMSK)

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.
