Matlab uses comma not ; Parameter names are without spaces. And you have an extra ) that doesn’t have a ( to match it.

Thanks Peng Li

Error in UFMC Modulation

qamMapper = comm.Rectangular*QAMModulator ('Modulatororder'), ...

[Peng Li]

I don't know the QAMModulator function, but just a guess based on your implementaion

qamMapper = comm.Rectangular*QAMModulator ( 'Modulator0rder' ),  ... % you have an extra ) here
           2^bitsPerSubCarrier, 'BitInput' ; true, ... % replace ; with ,
           'Normalization Method' ; 'Average power' ); % replace ; with ,

[kenny Ade]

qamMapper = comm.Rectangular*QAMModulator ('Modulator0rder' ...

2^bitsPerSubCarrier, 'BitInput' ; true ...

'NormalizationMethod' ; 'Average Power' ),

Am sorry Not working. please check double again the line again .

[Peng Li]

I think I said that matlab uses comma not semicolon. And again you’d better copy the complete error message here.

[kenny Ade]

qamMapper = comm.Rectangular*QAMModulator('Modulator0rder' ....
2^bitsPerSubCarrier, 'bitinput', true...
'NormalizationMethod', 'Avergae Power'),

Removed all semicolon, in the entire code but not working yet Peng Li. Xie, Xie.

[Peng Li]

You need a comma before ... and there isn’t a .... no meaning of this. And again you’d better copy and paste the entire error message here otherwise I can just guess. All what I mentioned are syntax errors.

ERROR: invalid expression when calling expression ..other wise check for delimeters

[Walter Roberson]

qamMapper = comm.RectangularQAMModulator('Modulator0rder', 2^bitsPerSubCarrier, 'bitinput', true, 'NormalizationMethod', 'Average Power');

and if you want to split it over several lines,

qamMapper = comm.RectangularQAMModulator('Modulator0rder', 2^bitsPerSubCarrier, ...
    'bitinput', true, ...
    'NormalizationMethod', 'Average Power');

Note that comm.RectangularQAMModulator is going away, and it is recommended that you convert to qammod(). See https://www.mathworks.com/help/comm/ref/comm.rectangularqammodulator-system-object.html#mw_7ac8462e-0cd3-43aa-a9ff-2033c3c46d37
