Synchronization on the basis of a period of time - frequency - correlation for a coherent ofdm - receiver

摘要

A device for synchronization of a pilot in symbols, the by means of a receiver in a more carrier - transmission system are received, as well as a corresponding method. A scheme on the basis of a period of time - frequency - correlation, the the time - frequency - correlation properties of the pilot, is for the identification of the positions of the pilot in the time - and frequency dimensions of the received symbols used. The apparatus comprises a pilot compensator and a signal selector for determining at least one correlation set, a correlator for generating a correlation set score for each of said correlation sets, and a determining unit for determining the positions of the pilot in response to said correlation set result.
