i need help!
how to simulate a gaussian noise and selective frequency fading channel in CDMA system?
please give me some reference book in this field
 

Re: matlab simulation

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

The book contains matlab functions which can be used to simulate fading channels.

best
