Patent ID: 7813456

Claim:
A method for synchronizing pilots contained in symbols received by a receiver in a multicarrier transmission system, the pilots having predetermined known values, being posited among data carriers in a frequency dimension containing the received symbols and having a predetermined position pattern in the frequency dimension, wherein the predetermined position pattern comprising a finite number of sub-position patterns each corresponding to positions of pilots contained in one of the symbols, the method comprising: determining at least one correlation set in the frequency dimension between two sub-carriers of at least one symbol at different frequencies; generating a correlation set result in response to each the correlation set; and determining positions of the pilots in the frequency dimension and time dimension in response to the correlation set results, wherein the pilots are posited among data carriers in the frequency dimension and a time dimension comprising of the received symbols and have a predetermined position pattern in the frequency and time dimensions, and wherein determining at least one correlation set comprises determining at least one correlation set in both of the time and frequency dimensions.
