Hi, this is how I solved the "unable to run" problem. I almost met all the problems mentioned in this dialog.
1) in matlab command window, cd C:/whereYourProjectRootFolderIs, thereafter 80211a_lib can be found. Simulink is unlike matlab, running a modle does not change the present working directory to the current one.
2) run 80211n.mdl, it asks for XXXXX2 models, for example "commdigbbndam2", change it to XXXXX3. change all the similar problem you met in the same way. Some are in 80211n.mdl, one is in 80211a_lib.mdl
3) in command window, type command slupdate('80211n',0). This would solve your "this and that cannot be found or cannot be initialized" problem.

Thank you for providing such a good module. But I need to use 802.11n to simulate multi-user transmission. What changes to how to use this module.

Hi Arya

I am facing the same problem and I am using the same MATLAB version as you (R2008b 7.7). Did you resolve this problem?

when I run this, I get an error regarding the "viterbi decoder" with in the "demodulator bank". something about "dectype not defined". I was wondering if someone can help me with this. I am using matlab R2008b (7.7) and R2007a (7.4). I have noticed that in my matlab I don't have a function commblkviterbi but I have commblkviterbi2 however after changing this line I still get the same error.
