Someone via email was asking me.
I know the AD9361 includes digital I/Q correction. Is there a document that describes how this is done inside the chip that is public?
In the Cal manual -- it states:
In the continuous running mode, the calibration will use RX data to minimize the quadrature error continuously.
but it doesn't say actually how? Is the algorithm documented anywhere? or is it magic/a secret (which is an Ok answer). I'm assuming it works better for some modulation schemes than for others...??
