Abstract:
The present invention relates to a method for the blind estimation of at least one parameter of an OFDM signal by maximizing an objective function depending on said parameter. The objective function implements a parameterized model of the OFDM modulation and a matched filtering corresponding to that model. The OFDM signal, baseband demodulated and then sampled in an observation window, is the object of the adapted filtering to calculate the objective function.It is also proposed to include, in the parameterized model, the temporal offset between the observation window and an OFDM symbol as well as the frequency offset between the frequency of the OFDM signal carrier and the baseband demodulation frequency.
