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). The last one would solve your "this and that cannot be found or cannot be initialized" problem.

Well mer baek after half a n h0our poking arround the block problem , I've just decide go the hard way open the 80211.a lib mdl anthe main mdl and serach an replace commdigbbndam2 with commdigbbndam3, now just my priblem is thentgn chanel canno't read teh.mat file for channel taps..

This demo supposed to use out-of-date communication library. It is commdigbbndam2.
I think Matlab does not support it any more.
So, there are many errors, when I try to run simulation.
If any one knows how to migrate this library to new one, please let us know.
I hope that the author is able to update this demo with latest matlab version.

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 everyone,
Whenever i run 80211nsimulink it shows error
Error in 'ieee80211n/MATLAB graphics/graphics' while executing M-File S-function 'IEEE80211n_udg', flag = 2 (update), at time 0.0034944. MATLAB error message:
Nonscalar arrays of function handles are not allowed; use cell arrays instead

Any idea?

Thanks in advance

Hi everyone,
Whenever i run 80211nsimulink it shows error
"Failed to find library 'commsequence2' referenced by 'ieee80211n/Demodbank/DecodeBankViterbi/Demodulator 1/Insert Zero1'. This library must be on your MATLAB path."

How can i get rid off this error...

Mr. Tokunbo Ogunfunmi

I downloaded this Simulink model but there is a problem in S- parameters of
Error in S-function 'ieee80211n/PER calculation/Variable Integer Delay': S-Function 'sdspvidly2' does not exist.

pls update, and pls help me in completing my project work ...
which is almost related to this simulink model...

i am searching for TGn Channel D model ...
for my project work...
