Abstract
A method is provided for adjusting at least one transmit parameter of a digital transmitter of a communication system by estimating phase noise of a sequence of symbols received in a demodulator of a digital receiver of the communication system. The method includes: measuring a phase for the symbols of the sequence, deriving a total phase error for the sequence from the measured phases, determining a characteristic of the total phase error, deriving, based on a signal quality estimation of the received sequence of symbols, an indication of a contribution to the characteristic from at least one impairment different from phase noise, obtaining a phase noise estimation by subtracting the indication of the contribution from the characteristic of the total phase error, adjusting the at least one transmit parameter depending on the obtained phase noise estimation.
