Communications Blockset Release Notes

Upgrading from an Earlier Release

If you are upgrading from an earlier release to the Communications Blockset 2.0.1, then note these issues:

• The Binary Symmetric Channel block dialog box now omits the Input vector length and Sample time parameters because the block now determines these quantities automatically. However, if you open a model in Release 12.1 that contains the Release 12.0 Binary Symmetric Channel block, then the Command Window might display warnings about block parameters. To suppress these warnings in the future, simply save the model from Release 12.1.
• In the Communications Blockset 2.0.1, any model that includes a digital passband modulator block or a digital passband demodulator block must use a variable-step solver rather than a fixed-step solver. To configure a model so that it uses a variable-step solver, select Simulation parameters from the model window's Simulation menu and then set the Type parameter on the Solver panel to Variable-step.

See Upgrading from an Earlier Release for upgrade issues involved in moving from the Communications Toolbox 1.4 (Release 11) to the Communications Blockset 2.0.1.
