Abstract
A method for synchronizing symbols at the output of a blind equalizer, the method being characterized by the following steps: on sending, inserting into a succession of sent symbols, one or more known sequences of symbols repeated in said succession of symbols; detecting said one or more known sequences at the output of said blind equalizer; deducing any shifting of the symbols at the output of the blind equalizer from the result of said detection; and retiming the symbols at the output of the blind equalizer as a function of the deduced shift.
Claims10
A method for synchronizing symbols at the output of an equalizer, characterized in that the equalizer is a blind equalizer and that the method comprises the following steps:
- on sending, inserting into a succession of sent symbols, one or more known sequences of symbols repeated in said succession of symbols,
- detecting said one or more known sequences at the output of said blind equalizer,
- deducing any shifting of the symbols at the output of the blind equalizer from the result of said detection, and
- retiming the symbols at the output of the blind equalizer as a function of the deduced shift.
A digital communications receiver including a blind equalizer, characterized in that it includes means for detecting, at the output from said blind equalizer, a sequence inserted into a succession of received symbols and means for deducing from the result of said detection any shifting of the symbols at the output of the blind equalizer and means for retiming the symbols at the output of the blind equalizer as a function of the shift detected.
