METHOD FOR PROCESSING AN ANALOG SIGNAL COMING FROM A TRANSMISSION CHANNEL, IN PARTICULAR A SIGNAL TRANSMITTED THROUGH POWER LINE COMMUNICATIONS

摘要

A method of processing an analog channel signal from a transmission channel, the analog channel signal (SAC) being capable of comprising a useful signal (SU) modulated on a subset of a set of available carriers, carrying at least one frame of symbols according to a frame structure and optionally noisy by at least one narrow-band noise signal (SB), the method comprising an analog-to-digital (CAN) conversion of the channel analog signal and a synchronization process comprising a filtering processing (MFL) including a time domain on-the-fly determination of a limited number of coefficients of a predictive filter of a self regressive model of a digital channel signal (CNS) derived from said conversion analog / digital and on-the-fly filtering of the digital channel signal in the time domain by a finite impulse response digital filter whose coefficients are those of the filter predictive, and detection of at least one indication (IND) for identifying at least one location of said frame structure, from the filtered channel digital signal (SNF) and a reference signal (SREF).
