| 摘要 |
The invention relates to a method to synchronise a multi-carrier transmission system wherein a time misalignment between a transmitter and a receiver is determined through an average of at least two pilot tones phase errors (Øi) weighted in accordance with the noise affecting each pilot tone transmission. Such method is characterised in that, when the noise affecting a pilot tone (38, 40) reaches a predetermined level, the pilot tone function is reallocated from this pilot tone (38, 40) to another carrier (42, 44) and/or this pilot tone weight is reduced.
