1. An apparatus, comprising:
- at least one processor; and
at least one memory including computer program code,wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least togenerate transfer function values of in-phase and quadrature channels;
determine compensation coefficients based on the generated transfer function values of the in-phase and quadrature channels; and
generate compensated frequency domain symbols for at least one frequency pair by using the compensation coefficients for compensating for frequency dependent distortion of a base band circuit.

Abstract
The invention is related to an apparatus which includes a first generator configured to generate transfer function values of in-phase and quadrature channels. The apparatus further includes a determiner configured to determine compensation coefficients on the basis of the generated transfer function values of in-phase and quadrature channels. The apparatus further includes a second generator configured to generate compensated frequency domain symbols for at least one frequency pair by using the compensation coefficients.
