addition of guassion noise and fading simulation is generic to and type od signal .
you need to generate random noise either by command or in simulink .
also by adding delayed ( by particular amount of samples) version of the signal in original signal you can also see the multipath fading effects on your signal.as in equation.
multipath version=s(n)+a s(n-k)
a lies between 0 to 1
k depends upon your model which yuo choose for simulation
more details can be found in simon haykin book for digital communication.

Hi hai chau,
please refer to this textbook http://www.edaboard.com/viewtopic.php?t=107173&highlight=patzold
The book contains matlab functions which can be used to simulate fading channels.
best
