| 20110293026 | METHOD FOR THE BLIND ESTIMATION OF OFDM MODULATION PARAMETERS ACCORDING TO A MAXIMUM LIKELIHOOD CRITERION - The present invention relates to a method for blind estimation of at least one parameter of an OFDM signal according to a maximum likelihood (ML) criterion. In one embodiment, the estimation method uses a deterministic maximum likelihood criterion. In another embodiment, the estimation method assumes that the modulation symbols modulating the sub-carriers of the OFDM multiplex are i.i.d. and Gaussian random variables. The estimation of said parameter is carried out while minimizing a cost function depending on the chosen criterion. | 12-01-2011 |
