I am trying to implement a periodogram in gnu radio.
Currently, I am stuck in deciding what sink i should use and how. I
want the output in the the form of an array so that I can have
calculations on the periodogram samples. As the input are the realtime
baseband samples from the USRP (here shown with a signal source), thus
the sink should be flexible enough to be updated. Thus I think that a
fixed length float vector sink doesnt suits here. I dont know how to
proceed from here
