commdigbbndam2 library is out-of-date library.
I think Mathworks does not support any more.
You can change each block in new communication library.
But you might not get the correct original parameter value.
Fortunately, this model is included in each Matlab Demo.
You can find it in Help menu.
Can someone help me about this model? 802.11a is part of my thesis, i am migrating from network simulator since i can't achieve proper results from ns2. i can't view the results of the simulation and how can i change the parameters? thank you!
