The platform of SDR is zedboard + AD9361
I fellow this page :IIO System Object [Analog Devices Wiki] to use the IIO System Object , and it works.
than I execute the Data Streaming Example in MATLAB (from AD Wiki page) and Data Streaming Example in Simulink
Although the hardware trans speed of received signal in Simulink looks normal , the speed in matlab code is very slow.
These videos can explain what I mean :
These video doesn't speed up or down , It's in real time.
The parameters of SDR hardware (such as sampling frequency ... ) are the same in both Matlab and Simulink.
In the third video , there is another problem . It must use pause command to plot the Constellation Diagram after stepImpl function.
Without pause , It can't plot any figure after stepImpl function has done.
What is the solution and how to use stepImpl function ?
I prefer Matlab to Simulink.
