I need to reduce the sampling rate below the nyquist rate on the zynq 7000 Zedboard with FMCOMMS3-EBZ. Do you know if it is possible to do it? Or do you have any path or articles that talk about it?

Hi,

I don't think there is much to do on the transceiver side. The AD9361 allows you to independent configure the analog bandwidth and the samplerate, so keep the analog bandwidth above your signals bandwidth and then reduce the samplerate.

You'll then have to implement signal processing to reconstruct the original signal from the compressed data. We do not have ready to use signal processing blocks the implement the reconstruction (how to do it partially depends on the signal of interest). But we do provide support for signal processing environments like MATLAB/Simlink and GNUradio where you could implement your processing algorithm. For more information please refer to the userguide section 5.3.
