Communications Blockset

Communications Sinks

The Comm Sinks library provides sinks and display devices that facilitate analysis of communication system performance. You can open the Comm Sinks library by double-clicking on its icon in the main Communications Blockset library (commlib), or by typing commsink2 at the MATLAB prompt.

Note    In this document, you can jump to a block's reference page by clicking on its icon below.

The table below lists and describes the blocks in the Comm Sinks library. For information about a specific block, see the reference pages that follow.

Block Name	Purpose
Error Rate Calculation	Compute the bit error rate or symbol error rate of input data
Continuous-Time Eye and Scatter Diagrams	Produce eye diagram, scatter, or x-y plots, using trigger to set decision timing
Discrete-Time Eye Diagram Scope	Display multiple traces of a modulated signal
Discrete-Time Scatter Plot Scope	Display a modulated signal in its signal space by plotting its in-phase component versus its quadrature component
Discrete-Time Signal Trajectory Scope	Display a modulated signal in its signal space by plotting its in-phase component versus its quadrature component
Triggered Write to File	Write to a file at each rising edge of an input signal
