APPARATUS AND METHOD FOR GENERATING DUMMY PILOT SIGNAL IN HARD HAND-OVER OF MOBILE TELECOMMUNICATION

摘要

An apparatus and method for generating a dummy pilot signal for a hard handover of mobile communication. The apparatus allows a Beacon device capable of supporting a hard handover in a synchronous Code Division Multiple Access (CDMA) wireless communication network to generate a dummy pilot signal using a Base Station (BS) classification Pseudo Noise (PN) synchronous signal extracted from a CDMA Radio Frequency (RF) signal of the BS. The apparatus acquires short PN code synchronization from the CDMA RF signal using a serial searcher scheme when the Beacon device generates a dummy pilot signal, such that a large number of gates are not required and a short PN code drift caused by a frequency shift of an internal oscillator can be compensated. Also, the apparatus allows the output dummy pilot signal to have frequency stability suitable for BS requirements, and solves problems of a conventional dummy pilot signal generation scheme, such that there is no need to receive an even clock signal (EVEN_CLK) and a reference clock signal from the BS.
