Communications Blockset 2.0.1 Release Notes

New Features

This section introduces the new features and enhancements added in the Communications Blockset 2.0.1 since the Communications Blockset 2.0 (Release 12.0).

For information about Communications Blockset features that are incorporated from the previous release, see New Features.

Setting Simulink Preferences Automatically

The new commstartup.m script sets certain Simulink preferences to values that are most appropriate for the simulation of communication systems. To use this script, type the command commstartup in your startup.m file or in the MATLAB Command Window.

Converting Between Bipolar and Unipolar Signals

The Utility Functions library contains new blocks that convert between bipolar and unipolar signals. The blocks are Bipolar to Unipolar Converter and Unipolar to Bipolar Converter.

Choosing Seeds for Random-Output Blocks

The randseed function is a new function that generates prime numbers for use as Initial seed parameters in blocks that produce random output. Compared to composite seeds, prime seeds yield output that has better statistical properties.

Using Error Counts to Control Simulation Duration

You can now configure the Error Rate Calculation block so that it automatically stops the simulation upon detecting a specified number of errors. You do not need to know in advance how long it will take to accumulate that many errors.

Choosing the Algorithm for Integrator Blocks

The Discrete Modulo Integrator block now allows you to choose the integration method using a mask parameter. The corresponding mask parameter in the Windowed Integrator block has changed its name from Method to Integration method for consistency with other integration blocks.
