Abstract
The present invention discloses a scattering-parameter estimation method for a transceiver of a half-duplex multicarrier communication system. The scattering-parameter estimation method includes steps of converting a first frequency-domain transmit signal to generate at least one symbol period of the first time-domain transmit signal; transmitting the first time-domain signal in a first specific time period; receiving and storing at least one symbol period of the first echoed signal of the first time-domain transmit signal in the first specific time period; converting at least one symbol period of the first echoed signal into a first frequency-domain echoed signal after a first transmission period; and estimating the S11 parameters corresponding to carriers respectively according to the first transmit signal and the first echoed signal.
