METHOD AND APPARATUS FOR ESTIMATING A SYMBOL TIMING OFFSET IN A WIRELESS COMMUNICATION SYSTEM TO PREVENT ESTIMATION PERFORMANCE DETERIORATION

摘要

PURPOSE: A method and apparatus for estimating a symbol timing offset in a wireless communication system is provided to prevent the estimation performance degradation of the symbol timing offset in the expanded CP (Cyclic Prefix) mode.;CONSTITUTION: By using the received pilot signal, the CIR (Channel Impulse Response) calculation unit(725) gets the RS (Reference Signal) CIR information and S- SCH (Secondary Synchronization CHannel) CIR information. By using the obtained S-SCH CIR information, the repetition ghost suppression unit](760) controls the channel elements except actual the repetition ghost of RS at the RS CIR information. The observation window generator(765) in advance establishes the observation range as the fixed length.;COPYRIGHT KIPO 2010
