Communications Blockset

RF Impairments

The RF Impairments library provides blocks that simulate radio frequency (RF) impairments at the receiver. You can open the RF Impairments library by double-clicking on its icon in the main Communications Blockset library (commlib), or by typing commrflib2 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 RF Impairments library. For information about a specific block, see the reference pages that follow.

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 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
