I/Q Imbalance to Compensator Coefficient

Converts amplitude and phase imbalance into I/Q compensator coefficient

Library

RF Impairments Correction

Description

The I/Q Imbalance to Compensator Coefficient block returns a complex coefficient to compensate for amplitude and phase imbalance.

This block has an amplitude imbalance input port and a phase imbalance input port, where the amplitude imbalance is a real number expressed in dB and the phase imbalance is a real number expressed in degrees. The imbalance inputs are vectors. The complex coefficients are returned from a single output port.

Algorithms

See iqimbal2coef for more information on the inputs, outputs, and algorithms.
