摘要
A method of determining non-ideality characteristics introduced on a signal by a transceiver is disclosed. The transceiver has an up-conversion transmitter and a down-conversion receiver. In one aspect, the method includes: 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, the second frequency being 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.
