Mobilstation und Zellwahlverfahren für Mobilkommunikation mit Kodemultiplexvielfachzugriff

摘要

A received signal (SR) of a control channel of each cell is despread by each spreading code in a correlation detector (22). The received level of the despread output in a window, including its peak, is measured in a level measuring part and an interference signal level outside the window is also measured. In a control part (25) the difference or ratio between the measured received level and the interference signal level is obtained as a comparison signal for each spreading code, and the comparison signal is compared in terms of magnitude to thereby determine the visited cell of a mobile station (20).
