16 point radix 4 DIT FFT

Can anyone design a simulink model for it. It will be very helpful for me. Thanks in advance!!

Thanks!!! by the way this link: https://www.mathworks.com/matlabcentral/fileexchange/22326-fixed-point-radix-4-fft, doesn't contains the simulink model for 16 point radix-4 DIT FFT.

The documentation for the contribution says,

radix4FFT3_FixPtEML.m is an Embedded MATLAB version of the radix-4 FFT that can be used in Simulink.

That is, it is an optimized Simulink model of it.

Okay, but could you please explain it in a more specific way. Thank you for your help and time in advance!!!

More specifically: radix4FFT3_FixPtEML.m is a Simulink model of the radix-4 FFT. It has been optimized, and it can even be used for code generation. You can invoke it from any Simulink model to perform its services.

There are basically four reasons to do this kind of work in Simulink:

1. You have a Simulink model that you need this kind of services as a component. radix4FFT3_FixPtEML satisfies this purpose; OR
2. You are working in Simulink because you need to deploy to target hardware or to Simulink Real-Time. radix4FFT3_FixPtEML statisfies this purpose; OR
3. You have been given a homework assignment to test your research skills, a "treasure hunt", where the point of the exercise is the search rather than the implementation. Your search skills led you to this forum, and the forum found radix4FFT3_FixPtEML for you, so radix4FFT3_FixPtEML statisfies this purpose; OR
4. You have been given a homework assignment to implement this as individual Simulink component blocks. No already-written model could possibly statisfy this purpose, as the purpose would be for you to design the implementation. If this is the purpose, then you had better get designing yourself, perhaps using the first link as design guideance.
