uint16_t | fp16_exp_adjust |
Operation structure for FFT processing.
The operation processes the data for multiple antennas in a single call (i.e. for all the REs belonging to a given SRS sequence for instance).
The output mbuf data structure is expected to be allocated by the application with enough room for the output data.
