How to input IQ data into Matlab/Simulink?

I have an SDR that outputs audio through a virtual channel, and Audio Device Reader can capture this. The same radio can output this data in complex form (IQ)and Audio Reader can't handle that. How can I get the IQ data into Simulink for processing as a complex signal? Thanks.

Hi Nina,

Can you further explain your workflow?

1. Is the SDR modeled in Simulink? 2. How are you capturing the I and Q part of the signal? audioDeviceReader reads audio sample. Are you getting two separate audios for I and Q?

Please elaborate.
