METHOD AND DEVICE FOR DEMODULATION WITH PHASE NOISE COMPENSATION

摘要

The invention concerns a method for demodulating a digital signal comprising complex time-based symbols, which include data transmitted on a plurality of frequencies, part of said data being known reference data, said method comprising at least a step including a main transformation step of the signal from a time base to a frequency base. The invention is characterized in that it further comprises, prior to said main transformation step, a step of estimating and compensating the phase noise on each symbol. The invention is in particular applicable to reception of OFDM or COFDM modulated television signals.
