OK! want the model for AWGN, and fading channel,
Matlab, simulink provides complete simulation model for rayleigh fading channel and for AWGN. After finishing your simulation with simulink you can make a exe file from your structure. Also you can tell matlab to give you it's C source code.
And I think this is really enough.
I have the book. However, it is not what i wanted... I plan to do simulation using simulink for a rayleigh and rain fading model. Simulink provides a good Rayleigh blockset, anyone knows how to model a rain fading channel?
