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 |
Purpose |
| 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 |
