Simulink reshape() block. https://www.mathworks.com/help/simulink/slref/reshape.html

Thank you

But the image can't see ok .

i attached model

[Walter Roberson]

Did you make sure to convert the image back to uint8 before displaying it?

[Johan Herreño]

no , i did not , mmm i am no sure, how can i do that ? other block ?

I converted to uint9 with that block, but modulator is displaying other error:

Error in 'ProcesamientoImagenes/M-FSK Modulator Baseband': When the 'Input type' parameter is set to 'Bit', the input must have a Boolean or double-precision data type.

Component:Simulink | Category:Model error

An error occurred while propagating data type 'uint8' from 'ProcesamientoImagenes/Reshape', output port 1.

I atached again my model

[Walter Roberson]

You are converting to uint8 too early. You should do that conversion after all the numeric processing, but before you display the image.

[Johan Herreño]

is that right ?

An error occurred while running the simulation and the simulation was terminated

Caused by:

• Error in 'ProcesamientoImagenes/M-FSK Modulator Baseband': Input must be an integer between 0 and M-1.

[Walter Roberson]

Remove that uint8 from where it is, and put it between the 8-FSK demodulator and the video viewer.

[Johan Herreño]

I have this configuration from source.

This is the result
