How can i change in a single bulk instruction all the instances of commdigbbndam2 to commdigbbndam3, without having to do it for every component (modulator or demodulator) by itself?
And another question is that when i save the model with the changes of commdigbbndam2 to commdigbbndam2 and i close it. Then i open it, i see that it opens the modules with commdigbbndam2 and not commdigbbndam3 and i have to do the update again. How could the library change remain ?
I really miss this model in the Matlab demos. I have demonstrated it every year for my students, and I developed a lab exercize based on this. Now we have to install a rather old version of Matlab to make it work. Please update this splended model and include it in matlab.
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.
Hi everyone !
"Jason sum" says we should change buffer module into non-frame based. is there anyone who knows that how can I change buffer module into non-frame based?
I am getting this error. Can anyone give a solution to this problem?

Hey Guys,
As I see, many of you have problem about loading "commdigbbndam2" library.
Lets change the missing library as "commdigbbndam3" one.
Take it easy !
Martina Wadie, I'm getting the same error: "Failed to load library 'commdigbbndam2' referenced by 'IEEE80211a/Demodulator/Demodulator 1/Rectangular QAM Demodulator Baseband'" did you solve it?
hi everyone
when I run the simulink, this error "Failed to load library 'commdigbbndam2' referenced by 'IEEE80211a/Demodulator/Demodulator 1/Rectangular QAM Demodulator Baseband'"
so can anyone help please ???

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!

Thanks. Email: isivri00@gmail.com
how can i change the "channel bandwidth" in this model, or change "subcarrier frequency spacing" ?
please help!
this is my email : kln.hichem@gmail.com
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.
Hi everyone,

Hi guys. You use Matlab 2007. I tested with Matlab 2007. It worked very good
jacj_2188@hotmail.com
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.
Does any one knows why do I get this error

Hi I am getting some errors when I try to run it on Matlab 7.10.0(R2010a. I believe the problem is related to version issues the error is :Error in 'IEEE80211a/Demodulator': Initialization commands cannot be evaluated.
can anyone help me to fix it.
thanks
thank you. But it use for OFDM.
I want to find "adaptive modulation and coding" use for HSDPA. Could you help me ?
Any one having expert ideas in evaluating code performance on dsp kit c6713..
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!
thank you, this is great! is there any updated version of this? 'feval' function seems to not be supported in recents matlab versions. has anyone solved the error message in the IEEE80211n_udg file??

Very nice work, but its utility for learning is crippled by lack of any documentation whatsoever.
I ran the model, and i have to say that it's a good.But is it possible to get the documentation for the model.I'll really appreciate it.
Thanks.
Please send me its documentation. Its a very good and detailed model.
Bernd St (stuerzibernd@googlemail.com)
yes, did solve it, you have to slect in matlab current directory and put where are the directory of R13SP1, aftes that, open Simulink and clik in open a model, and choose the IEEE80211a.mdl, and Run.... that's all, bye.
I think it's a very good model. Unfortunately I have the same error as Felipe (posted 2008-04-30) with the Doppler-Filter. Do you have a solution for that. Anotherpleasure to you: Can you sent me the documentation too, to understand the project.
thx,
Bernd
ok
Very good model. It is helping me alot to get a grip of the 802.11a standard. I would be very grateful if you can send me the documentation files so that I can understand your project.My objective is to change the multipath model with another model which I have already in hand.
i'cant run ths program, I have a problem with a Filter....and this is: Error in 'IEEE80211a/Multipath channel/Multipath Rayleigh Fading Channel1/Multipath Fading Channel/Fading Profile/Triggered Rayleigh Profile/Doppler Filter': Initialization commands cannot be evaluated.

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?
Runs for me just fine.
One question, is the convolutional encoder/decoder hidden? I dont see it anywhere.
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.
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?
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,
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??
I have all the required toolboxes (Communications,Communications Blockset,DSP Blockset,Signal Processing,Simulink) but it
I get an error message saying invalid stateflow license and does not run
it doesn't seem to run!
