Abstract:
A system for a mobile radio system having a base station and an antenna device, comprising:a digital signal controller provided in the base station which, in the case of transmission, divides a digital signal to be transmitted into n individual digital signals which have essentially the same amplitude and frequency but have different phase angles, and which, in the case of reception, forms a composite reception signal with a uniform phase angle from the n individual signals; n ports provided in the base station; a device provided in the base station to convert the n individual signals of the signal controller into n analog, carrier-frequency radio signals for the n ports of the base station and vice versa, the carrier frequency radio signals having essentially the same frequency and amplitude, but different phase angles decoupled from one another; a combination/division device having a port and arranged between the base station and the antenna device to connect the base station and the non-adaptive antenna device such that in the case of transmission, the carrier frequency radio signals are combined to form a composite signal which is provided to the port of the combination/division device and fed to the antenna device as an antenna signal, the composite signal having a uniform phase angle, and in the case of reception, the combination division/device receiving the antenna signal as the composite signal with uniform phase angle and dividing the antenna signal into the n carrier frequency radio signals which have essentially the same frequency and amplitude but different phase angles, the n carrier frequency radio signals being fed to the n ports of the base station.
