I have used the Loop>>> txSigFOFDM = filtTx([txSigOFDM; zeros(L-1,1)]); why matlab shows an error?

txSigFOFDM = filtTx([txSigOFDM; zeros(L-1,1)]);

Error Message:

Array formation and parentheses-style indexing with objects of class 'dsp.FIRFilter' is not allowed.  Use objects
of class 'dsp.FIRFilter' only as scalars or use a cell array.

Error in fofdmn1 (line 72)
txSigFOFDM = filtTx([txSigOFDM; zeros(L-1,1)]);

Same reason as your other question: you are trying to use a syntax that is not supported in your R2015a version. You need to use step instead

txSigFOFDM = step(filtTx, [txSigOFDM; zeros(L-1,1)] )

You should be looking at the documentation for your version, not at the R2017b documentation.

Thank you sir. You answer me correctly.

Can you share the code for F-OFDM model ?

[Walter Roberson]

Yes, I can share code for F-OFDM models; however I do not have any code for F-OFDM models.

[David Webb]

Walter Roberson, Thats good. email me the code @ [e-mail].

Thanks in Advance.@Walter Roberson

I can eat Baked Alaska. It is legal for me to eat Baked Alaska (and it is also enjoyable.)

I cannot eat the elm tree in front of my house. It is not legal for me to eat elm trees in my city: they are a protected species. (And there is also the problem that elm trees are mostly indigestible.)

Unfortunately, there is no Baked Alaska at my house. I have not seen Baked Alaska for about 35 years. The only place in the city that was thought just might still serve Baked Alaska, closed down about 7 years ago. In order to send you some Baked Alaska, I would have to hire someone to make some Baked Alaska in the first place.

The elm tree, on the other hand, drops its branches and generally makes a mess. I have some in the yard that I would be happy to get rid of. However, I can't send you any the elm tree: the city is worried about spreading Dutch Elm Disease, so I have to save the branches and wait for the city to collect them.
