SYMBOL TIMING SYNCHRONIZATION METHOD AND APPARATUS ROBUST TO FREQUENCY OFFSET IN WIRELESS COMMUNICATION SYSTEMS

摘要

PURPOSE: An apparatus and a method for obtaining symbol synchronization robust to frequency offset in a wireless communication system are provided to reduce complexity of a receiver for obtaining symbol synchronization by assigning a synchronous pattern for obtaining symbol synchronization to a synchronous channel. CONSTITUTION: A sequence generating part(101) generates a base sequence for obtaining symbol synchronization. A synchronous pattern generating part(102) generates a transformation sequence based on the base sequence. The synchronous pattern generating part generates a synchronous pattern by assembling the transformation sequence and the base sequence. A frequency mapping part(103) generates a transmitting frame by mapping transmitting information to a time and frequency domain based on the synchronous pattern. A transmitting part(104) transmits the transmitting frame. A synchronous pattern generating part generates the synchronous pattern by variously setting ratio between the base sequence and the transformation sequence included in the synchronous pattern.
