1. An apparatus comprising:
a first transceiver for operable communication over a first communication protocol;
a second transceiver for operable communication over a second communication protocol, wherein the second transceiver comprises:
a first receiver chain, and
a second receiver chain, wherein the first and second receiver chains are for receiving a leakage signal corresponding to a training signal transmitted by the first transceiver over a set of frequencies;
a processing device for computing at least one whitening filter value based on the leakage signal for each of the set of frequencies; and
a whitening filter applicable to receive signals received by the second transceiver.
