摘要： A method and arrangement for estimating a carrier frequency offset for a data transfer from a receiving system entity in a mobile communication network. User data associated to a predefined user i, is extracted (200) from the transferred data, and transformed (202) into a time domain. A resource symbol phase offset θ 1 between two resource symbols representing the same user, is estimated (204) from the transformed user data, and a resource element phase offset θ 2 is between two resource blocks occupied by the same user is estimated (206) from the transformed user data. Finally the carrier frequency offset is estimated (208) based on the resource symbol phase offset θ 1 and the resource element phase offset θ 2 . By estimating a resource symbol phase offset θ 1 and a resource element phase offset θ 2 , an accurate carrier frequency offset with a larger range can be estimated.

摘要： The present invention relates to a method for estimating a timing error and a frequency offset in a high-speed portable Internet system and a method thereof. A predetermined preamble symbol is added to an OFDM frame to be transmitted by a transmitter according to an exemplary embodiment of the present invention, an IFFT operation is performed, and then a pseudo noise is multiplexed by the preamble symbol to estimate the timing error and the frequency offset. A receiver receives an OFDM symbol, extracts the preamble symbol from the OFDM symbol, and multiplexes the extracted preamble symbol by a local pseudo noise, which is equal to the pseudo noise used by the transmitter but is shifted.
