    摘要: The invention relates to a method for increasing the precision during the determination of system parameters dependent on the propagation delay, e.g. for a positional determination, in a mobile communications system with emission diversity, according to which a subscriber data signal and a reference signal are assigned to a subscriber. The subscriber data signal is emitted by at least two antenna devices on the emission side, whereas the reference signal is emitted exclusively by one antenna device on the emission side. The reference signal is used to precisely determine signal propagation delays, upon which the system parameters depend.

    摘要: The communications system operates at two distinct operating modes. Each of the slave stations, which are controlled by a master station, has a first output circuit and a second output circuit. The two output circuits are connected to one another on the output side. In a first operating mode, the slave stations are identified by the master station, all the first output circuits can be activated and the system operates at a low clock rate. In a second operating mode, a transfer of data takes place, one of the second output circuits can be activated, and the system operates at a higher clock rate.
