matlab project for handoff
Physical channel is just like using a random bernoulli data source or you can specify your self what to send. Of course you would have CRC, Interleaving, Modulation etc this would be different if you are using Traffic channels and Signalling channels. Now a way to use Statefow is through Simulink so you will have to design a simulink model. Try to see the following posts on mathworks.com
1) power control (there are 2 at mathworks.com but choose the one which has stateflow)
2) Mobile call processing
I'll try to help you whenever I find the time in between. Keep me posted at my email address
