Complex symbols in AD9361 bandwidth and addition of FFT in reference design

Hi everyone,

 

 

I am currently trying to insert an IFFT in the reference design and i would appreciate if someone could please answer to these questions i found.

 

1 -> Since in the data files page it is said that each 32 bit word corresponds to a complex symbol (that i assume means that the I and Q carriers mare generated), i woud like to know if the frequency of the generated symbols is set in the set_tx_bandwidth() function?

 

2 -> If both the input and output of the FFT are in 16 bit format, should i insert this block between the upack and rfifo cores?
