Digital Baseband Modulation

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. clicking on one of the icons below jumps to an overview of that sublibrary.

Digital Baseband 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; for a discussion of digital baseband modulation capabilities, see Digital Modulation.
