New Features

This section summarizes the new features and enhancements introduced in the Communications Blockset 2.5:

If you are upgrading from a release earlier than Release 12.1, then you should also see the Communications Blockset 2.0.1 Release Notes, starting with New Features.

RF Impairments Library

The new RF Impairments library contains blocks to simulate radio frequency (RF) impairments at the receiver. The blocks in the library are listed in the following table.

Block Name 
Free Space Path Loss
Reduce the amplitude of the input signal by the amount specified
I/Q Imbalance
Create a complex baseband model of the signal impairments caused by imbalances between in-phase and quadrature receiver components
Memoryless Nonlinearity
Apply a memoryless nonlinearity to a complex, baseband signal
Phase/Frequency Offset
Apply residual phase and frequency offsets to a complex, baseband signal
Phase Noise
Apply receiver phase noise to a complex, baseband signal
Receiver Thermal Noise
Apply receiver thermal noise to a complex, baseband signal
