Abstract
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.
