I am receiving signal from USRP using MATLAB, but I only want to receive the signal of a particular device ie: Micaz how can I do that when multiple devices in the room are operating at the same frequency?

Would this be inside Simulink, or using MATLAB-level functions?

I have written the Code of Matlab function to receive IQ sample of signals so that is in Matlab-level function!

If you have the cooperation of the device you want to talk to, then see techniques such as those described at https://www.mathworks.com/help/supportpkg/usrpradio/ug/packetized-modem-with-data-link-layer.html . That permits you to create data links -- so each packet of data to be sent out would be tagged with it source and destination link address, and data that is not part of the flow should (ideally) be dropped by the link. Or at the very least you would be able to tell where the packet is from and drop the packet.
