How to convert complex float file to complex int 16 in Gnuradio For USRP input...

In Gnuradio there are different types that you can see in the below screenshot? How to convert complex float file to complex int 16 in Gnuradio For USRP input I need to convert complex float to complex int... , My question is how can I do this action? Thanks in advance [image: Screenshot from 2022

Re: Why when I send a complex file with harmonic sequence f1 f2 f3 ...fn, In receiver haromoic sequence gain is changed?

I mention that problem is not related to USRP, it is a bug in my code and calculations.USRP sends complex samples high-quality less for short distances... Thanks very much On Sun, May 8, 2022 at 2:38 PM sp h wrote: > With this description for removing this frequency-selective channel wh

Why when I send a complex file with harmonic sequence f1 f2 f3 ...fn, In receiver haromoic sequence gain is changed?

Why when I send a complex file (With USRP x300) with harmonic sequence f1 f2 f3 ...fn, In receiver (USRP x310) harmonic sequence gain is changed? For example, I have a complex file the FFT of a signal has some harmonic peaks f1 f2 ...fn gain of harmonic peaks in the original file is: f1:2 f2:2 f3:3
