METHOD AND APPARATUS FOR DETECTING A CELL IN AN ORTHOGONAL FREQUENCY DIVISION MULTIPLE ACCESS SYSTEM |
摘要 |
<p>An apparatus and method are provided for detecting via a mobile station a cell in which the mobile station is located in order to initiate communication in an Orthogonal Frequency Division Multiple Access (OFDMA) system including a plurality of base stations transmitting signal with a pseudo-random noise (PN) code to the mobile station. The apparatus and method include receiving the signal from the base station and performing fast Fourier transform (FFT) on the received signal; generating a PN code for comparison with a base station's PN code included in the signal; and detecting a cell where the mobile station is located by searching for a PN code synchronized in the FFT-processed signal using the generated PN code.</p> |
