APPARATUS AND METHOD FOR ACQUIRING TIMING AND DETECTING CELL ID IN WIRELESS COMMUNICATION SYSTEMS

摘要

PURPOSE: An apparatus and a method for obtaining synchronization and searching a cell id in a wireless communication system are provided to design a preamble with superior performance while reducing complexity when using an OFDM 1 symbol. CONSTITUTION: Remaining binary time domain preamble sequences except a binary time domain preamble sequence for obtaining synchronization predetermined among binary time domain preamble sequences which can be generated by an IFFT(Inverse Fast Fourier Transform) operation about a binary frequency domain preamble sequence using the frequency domain preamble sequence and the binary time domain preamble sequence. The determined remaining binary time domain preamble sequences and the predetermined binary time domain preamble sequences are transmitted to a terminal(303).
