Communications Blockset

Communications Sources

Every communication system contains one or more sources. You can find sources in Simulink's Sources library, in the DSP Blockset's DSP Sources library, and in the Communication Blockset's Comm Sources library.

You can open the Comm Sources library by double-clicking on its icon in the main Communications Blockset library (commlib), or by typing

commsource2

at the MATLAB prompt.

Source Features of the Blockset

Blocks in this library can:

• Generate random or pseudorandom signals
• Generate nonrandom signals by reading from a file or by simulating a voltage-controlled oscillator (VCO)

This section describes these capabilities, considering first random and then nonrandom signals.
