Base station circuit for mobile radio communications system analogue carrier frequency signals provided by base station combined for providing signal for non-adaptive antenna

摘要

The base station circuit has a digital signal control device (2) within the base station (1) for splitting the digital signal (SF) to be transmitted into a number of individual signals (S1,S2,..) with the same amplitide and frequency and for combining a number of received individual signals into a sum reception signal (SR). The individual signals are converted before transmission into analogue carrier frequency radio signals, supplied to a non-adaptive antenna (5) via a device (4) for combining the individual signals to provide the antenna signal (AntS) and for separating the signal received from the antenna into several analogue carrier frequency radio signals.
