Sir, I am trying to loopback a signal from ad fmcomms3 ebz using zedboard. I am transmitting an LTE signal, 5MHz bandwidth and 15.36 MSPS sampling saved in a mat file in the form of I +jQ and transmitted at a center frequency of 2.4 GHz. The signal is transmitted and captured using adi iio oscilloscope. I am facing the problem that the nmse of the received signal is only -6db. Has anyone tried the same using zedboard and ad fmcomms3 ? Also please mention if anyone has achieved better nmse values with the same devices. Thank you
