Relative calibration has been proposed as a simple
way to practically exploit the reciprocity of the wireless channel.
It is based on a simple convolutional model for the relationship
between the channel impulse responses in both directions, and ac-
counts for the discrepancies between transmit and receive radio-
frequency components, without the need for specific calibration
hardware. However, the relative calibration methods developed so
far have been shown to lack robustness with respect to frequency
offset between the devices on both sides of the considered channel.
In this article, we introduce a relative calibration algorithm that
properly deals with the presence of frequency offset. We verify
its robustness and assess its performance through simulations,
and validate experimentally the proposed model on measured
channel reciprocity, relative calibration
