METHOD FOR FINE SYNCHRONISATION ON A SIGNAL RECEIVED FROM A TRANSMISSION CHANNEL

摘要

The invention concerns a method for fine synchronisation on a reception signal (S) corresponding to a reference signal (TS) transmitted in a transmission channel, comprising the following steps: selecting a signal source producing a characterisation signal (X) following its passage in the transmission channel; establishing a characterisation matrix (L) to estimate the characterisation signal (X) covariance; identifying characteristic modal values which are the highest characteristic values ( lambda i) of said characterisation matrix (L); computing the source signal correlation function c(t) with the sum of characteristic vectors (vi) associated with the characteristic modal values; searching said correlation function c(t) first maximum.
