    • A method for disturbance-free operation of at least two base stations working according to the CDMA (Code Division Multiple Access) principle in a universal mobile telecommunications system, preferably in-house base stations, with partially overlapping radio fields relative to one another and/or with respect to a telecommunications radio cell network, wherein, the base stations transmit the communications information using the CDMA multiple access method, at least two participating stations carry out an autosynchronization procedure for the purpose of eliminating disturbing interferences on account of the overlapping radio fields and identical transmission frequency, chip synchronism being produced as a result and, consequently, good reception of the orthogonal codes, i.e. good subscriber separation of the multiple access method, is ensured.
    • 一种在通用移动电信系统(优选室内基站)中根据CDMA(码分多址)原理工作的至少两个基站的无扰动操作的方法,其具有相对于彼此的部分重叠的无线电场和/ 或相对于电信无线电小区网络,其中,基站使用CDMA多址方法发送通信信息,至少两个参与站执行自动同步过程,以便消除由于重叠的无线电场的干扰干扰 并且相同的传输频率,因此产生了芯片同步,因此确保了正交码的良好接收,即,多路访问方法的良好的用户分离。
