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.
