A method of determining non-ideality characteristics introduced on a signal by a transceiver is presented. The transceiver comprises an up-conversion transmitter and a down-conversion receiver. The method comprises the steps of: a) generating a signal comprising at least one known training symbol, b) up-converting this signal with a first frequency to a first signal in the transmitter, c) transferring the first signal from the transmitter to the receiver, d) down-converting with a second frequency this transferred first signal to a second signal in the receiver, whereby the second frequency is different from but linked to the first frequency, e) detecting at least one of the training symbols in the second signal; and f) separating, in the frequency domain, at least one of the components of at least one of the detected training symbols for determining the non-ideality characteristics.
