I have a number of questions related to I/Q balancing.
Not being a math genius, I am having trouble trying to figure out how to compensate for I/Q imbalances in software. Are there any good strategies for balancing the amplitude and phase differences between the I/Q channels in software?
This is done in PowerSDR , I looked at the PowerSDR source code but it disappears into a dll for the phase and amplitude compensation detection. Does anyone know how they do it?
What would be a good display for checking I/Q balance? How would you compute it?
And my last question Does anyone have a manual or Doc's for the old Intel signal processing lab(NSP)? It seems that they have changed to IPP and I can no longer find any info for the old DLL.
Thanks
