GNU Radio block to correct IQ imbalance in quadrature receivers
It's composed of two main block:
- fix : Given a phase and amplitude error, it will correct a complex signal
- optimize: Attempts to auto-detect the phase and amplitude error to feed to the fix block above
The gr-osmosdr driver can make use of this block automatically if gr-iqbalance is installed prior to gr-osmosdr.
