Abstract
A receiver for an MCM signal with pilot symbols, comprising a first phase adjustment unit for adjusting the phase of an MCM signal by means of the pilot symbols and to output a first phase adjusted MCM signal to an MCM re-modulator unit which demodulates and then modulates the first phase-adjusted MCM signal to create an MCM reference signal. The communications receiver also comprises a second phase adjustment unit which receives the first phase adjusted MCM signal and also the MCM reference signal. The second phase adjustment unit adjusts the phase of the first phase adjusted MCM signal by means of said MCM reference signal and outputs a second phase adjusted MCM signal to an output MCM demodulator which demodulates the second phase adjusted MCM signal and outputs the demodulated MCM signal.
