Neighbor Cell Search scheme and method for W-CDMA Mobile station

摘要

The present invention relates to a search apparatus and method for the mobile station to effectively search for a neighbor base station in preparation for soft handover in an asynchronous W-CDMA system.;In the asynchronous W-CDMA system, the neighbor base stations must be constantly searched for soft handover. In the conventional method, the first method has a simple mobile station receiver structure, but the neighbor base station search performance is very poor. Although the performance is very good, there is a disadvantage that the power consumption of the mobile station is very large due to the large amount of computation.;The present invention is an improved method of the second conventional method, which can maintain a high performance while reducing the amount of computation. This invention can be applied to the receiver of the modem of the IMT-2000 commercial terminal.
