A base station for a radio communications systems contains at least one carrier-related transceiver device and at least one central unit for controlling the base station. The transceiver device and the central unit each contain at least one interface device which are connected by at least one individual line in accordance with a point-to-point connection for transmitting traffic data. Therefore, point-to-point connections with individual lines for each transceiver device that do not need to satisfy the requirements of identical lengths are used instead of a bus structure. In this way, an essentially more cost-effective implementation of the transmission of traffic data between the central unit and transceiver device is possible because the data rate can also be increased in accordance with the length of the individual line. A logic bus structure is mapped onto physical point-to-point connections. Traffic data, o&m data and also synchronization data are transmitted using the bus structure. The base station is suitable for use in radio communications systems with GSM, TDMA, CDMA radio interfaces, or other radio interfaces.

A method and apparatus for detecting items of information transmitted according to the DS-CDMA principle in a receiver apparatus. According to the invention, the detection of items of information transmitted according to the DS-CDMA principle ensues in a receiver apparatus in that, given the presence of the spread codes of at least two connections, the items of information related to the individual connections are separated in a first step, and an individual equalization of the items of information related to the individual connections ensues thereupon. The invention can be used advantageously in mobile radiotelephone terminal apparatuses and base stations that operate according to the CDMA principle.
