Hello all
Thanks for sharing the very valuable and useful simulink models.

Regarding the last mentioned problem, which appears once you double click on the Signal Visualization block.
Error message ('IEEE80211a/MATLAB graphics/graphics' while executing MATLAB S-function 'IEEE80211a_udg', flag = 2 (update), at time 0.0.
CELL2MAT does not support cell arrays containing cell arrays or objects.)
Solution:
1. Go to IEEE80211a_graphics.m file.
2. Comment the following line:
haxes = cell2mat(struct2cell(ax));
3. Add the following two lines instead of the commented one:
A=struct2cell(ax);
haxes=[A{:}]';
4. Add the following at line 29:
d.plotfn_handles = {};
5. Finally, inside the for loops, modify the lines 31 and 65 as follows:
d.plotfn_handles{n} ...
instead of: d.plotfn_handles(n) ...
and
d.plotfn_handles{i} ...
instead of: d.plotfn_handles(i) ...
Respectively.

And enjoy :)

I am getting the same message as Aamir :

Error in 'IEEE80211a/MATLAB graphics/graphics' while executing MATLAB S-function 'IEEE80211a_udg', flag = 2 (update), at time 0.0.
CELL2MAT does not support cell arrays containing cell arrays or objects.

I can't see deep enough or any further into the problem to solve it. As such the error reporting is poor. For instance the supporting 'IEEE80211a_udg.m file does not itself contain the Cell2MAT function, it must be calling a built-in function incorrectly,, but where.

Hey Guys,

Hello, thank you very much for your toolbox but I encoutered several errors like others and just followed their solutions : (commdigbbndam2 => changed into commdigbbndam3 and a other one regarding the fading channel here too, I just changed the lib into XXX3) now the simulation seems to work but when I try to visualize the signals I get this error :

Error in 'IEEE80211a/MATLAB graphics/graphics' while executing MATLAB S-function 'IEEE80211a_udg', flag = 2 (update), at time 0.0.

Nonscalar arrays of function handles are not allowed; use cell arrays instead.

It seems to be related to this .m file : IEEE80211a_udg.m

Does anyone can help me? I did not change anything in the simulink model or code except update the lib above.

Is it possible to get any documentation of this toolbox ? (My email adress : anthonytrioux59@gmail.com)

Many Thanks!

I also have Matlab 2016a, and when I try to run this code, it says the error message like everyone else has here. I "solved" it and hope you can benefit from the code.

1. commdigbbndam2 is not supported in the latest version, instead commdigbbndam3 is used, so you only need to change the library to the latest module.
2. There's an error in Rayleigh fading channel, I just comment out the channel, and the only left is AWGN, hope it won't affect the performance.
3. The buffer module needs to change to non-frame based, which is easy to find.

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.

to solve the compatibility question with matlab 7 or more just don't use "feval" but call functions by yourself. i know, this is for lazy people: for example in IEEE808211a_udg.m change it like that:

%feval{bd.plotFcnHandle, plot_data, bd.axes, bd.firstcall, other_params};

IEEE80211a_graphics(plot_data,bd.axes, bd.firstcall, other_params);

the same work has to be done in in IEEE80211a_graphics.m also.

good luck!

Even I am running Matlab 7.0 and am having trouble with the same IEEE802.11a_NoSF model.Can anyone help me fix this problem?

Error in 'IEEE80211a_NoSF/Multipath channel/Multipath Rayleigh Fading Channel1/Multipath Fading Channel/Fading Profile/Triggered Rayleigh Profile/Doppler Filter': Initialization commands cannot be evaluated. MATLAB error message: Invalid setting in Digital Filter block (mask) 'Doppler Filter' for parameter 'MaskEnables'.

I am running Matlab 7.0 and am having trouble with the IEEE802.11a_NoSF model. The following error is thrown. I looked at the Doppler filter block and was unable to locate the parameter. Can anyone help me fix this problem?

Good project!
But I don't know how the model of "Simulation Settings" is implemented.
Who can explanation it to me?
Thanks a lots.

frank lee

good job! very helpful to me! thank you

Luis F

Very good project!, but it would be possible to get more information or any documentation about how was it implemented. I will appreciate if you can send me a more detailed explanation for this model. Thanks

Ritz Goel

It is really a very good project but the theorotical discription on the first page is very less.From where can I get more tutorial for this implementation and the source code?

Kelvin Chee

Where can I get the IEEE80211a_sfun.m instead of DLL file?

Raul Jimenez

It is very interesting, but i need the code files, how i can get it?

I am interested in observing the performance of the system.I downloaded the file,unzipped it and set the directory path the folder, but I could not open the IEEE802.11a_noSF.mdl file.system says:Warning: Simulink<-->Stateflow inconsistency found, attempting repair...
Repair completed.

Corrupted Stateflow charts are recovered and placed in a subsystem named

IEEE802.11a worked fine.I have a question .The input data which send to zero pad in modulator is 4320*1,but the output of the zero pad is 960*1,that means truncation uccured and some of the input data are abandoned. Isn't right? If yes,how can it calculate the PER correctly?

John Oliver

Runs for me just fine.

One question, is the convolutional encoder/decoder hidden? I dont see it anywhere.

Phang Kok Hong

I am interested in observing the performance of the system.I downloaded the file,unzipped it and set the directory path the folder, but I could not open the IEEE802.11a_noSF.mdl file. I am using MATLAB 6.1. I am not sure whether is it because of the MATLAB version that I am using now?? Any help is very much appreciated. Thank you in advance.

Yongtao Wang

IEEE802.11a_noSF.mdl worked fine. But IEEE802.11a.mdl did not work. There was an erros message "make: fopen: IEEE80211a_sfun.mku: No such file or directory". Also, seems to me there are many things hidden in the model. Can someone provide a short tutorial so that it would become more understandable?

beatriz romero

i downloaded the model of 802.11a and i tried to open it (i tried to
open ieee802.11a_noSF.mdl) in my pc and i couldn't.
it seems to be empty but i know it isn't becase its size is aproximatly 256KB.
i am very interestig in that model and i would like to open it.
please i'd be very grateful if you could help me,
thaks in advance,

randy kuo

Pepe Viyuela

I could run it. With Matlab 6.5. And it is great.

Unable to open model file 'dspsigops.mdl'
help me!
what and where is it??
