Claim:
1. A method for processing an analog signal from a transmission channel, the analog signal comprising a useful signal modulated on a sub-set of carriers from a plurality of available carriers, the useful signal carrying at least one frame of symbols according to a frame structure, the useful signal susceptible to noise, the method comprising: analog-to-digital converting of the analog signal into a digital signal; synchronizing the digital signal, the synchronizing comprising determining, in a time domain, a number of coefficients of a predictive filter from an autoregressive model of the digital signal, the number indicating a quantity of coefficients of the predictive filter, and filtering the digital signal in the time domain by a digital finite impulse response filter with coefficients based upon the number of coefficients to provide a filtered digital signal; and detecting at least one indication for at least one location in the frame structure to be identified based upon the filtered digital signal and a reference signal.
