I am attempting to use the IQ correction to correct for images in my project. Specifically for the attached flowgraph I want to replace the scheme I now have in place using the 3 Multiply Constant blocks and the Add block. This scheme results in am image that is –44 dBc down. Uncorrected the image is –20dBc.
I tried using the IQ Correction block but nothing changed from the uncorrected image. I tried small values for the correction such as I am now using. When that didn't improve things. I tried increasingly larger values.
Nothing changed.
What am I doing wrong?
