发明名称 APPARATUS FOR GENERATING PERIODIC BEACON SIGNALS FOR USE IN A CDMA BASE STATION
摘要 <p>An apparatus for generating a plurality of beacon signals for use in a code division multiple access (CDMA) base station includes: a level controller for controlling a level of each of a plurality of transmit intermediate frequency (TxIF) signals based on a level control signal, thereby generating level-controlled TxIF signals; a frequency converter for converting a frequency of each of the level-controlled TxIF signals received from the level controller based on a frequency control signal, thereby generating a beacon transmit radio frequency (TxRF) signal time-divisionally; a time division controller for generating the level control signal and the frequency control signal based on a system synchronization signal and predetermined control information; and a control information storing unit for storing the predetermined control information.</p>
