I was wondering if it's possible to change the input order for the FFT block to receive all Q,I samples of a channel first, all Q,I samples of the next channel and so on, instead of being interleaved as I see with default configuration. The issue is that my data that arrives from an LVDS is saved in that order, and changing it to meet the default input consumes more resources like BRAM, that maybe changing the input order. If the input change can not be done, do you recommend to use nFFT blocks in parallel, or use a memory to reorder the samples?
Thank you and best regards,

Please see if "axi4-stream subset convertor IP" is useful for this..
