摘要： A combiner circuit employs the maximum power method, in which the phase of one of the signals is varied such that the power of the aggregate signal (main and diversity) is varied such that the power of the aggregate subsequently formed is optimally high. In order to improve this combining method that becomes less and less efficient with increasing bandwidth and number of steps of signals, particularly given selective fading, it is provided that the combiner circuit contains a control circuit for the combination phase, the control circuit being composed of a maximum power control circuit and of two preceding, supplementary circuits for varying the amplitudes of the main and diversity signals. The amplitude variation of the main and diversity channel spectrum occurs in such a fashion that the signal spectra are split in the appertaining branches of the two supplementary circuits by respective identical bandpass filters for the lower spectrum half and the upper spectrum half, the powers of the sub-bands are measured at the outputs of the bandpass filters and both sub-bands are set to approximately identical values.

摘要： According to the invention, a base station has an antenna device with a plurality of antenna elements and is connected to a subscriber station via a radio interface. The direction of incidence, the attenuation and the delay times of connection paths used for beam forming for signal sections for channel estimation purposes are determined from the transmissions of the other radio station in a known manner. The beam-forming vector for the transmit signal is constant during these signal sections for channel estimation purposes, for which the radio station can estimate a reception characteristic of the other radio station. Outside the signal sections for channel estimation, a symbol-specific beam-forming vector is determined which takes into account variable symbol-related properties of the transmit signal (for example correlation properties of CDMA codes) which are not constant during a time slot but rather vary from symbol to symbol.

摘要： A method transmits signals of a link between a transmitting station and a receiving station of a radiocommunication system, wherein at least one pilot signal is transmitted between the stations NB and UE in order to enable estimation of at least one channel of said link by the receiving station. The channel estimation results are determined in order to detect data to be transmitted to the receiving station by means of the signals of the link. Deviation between the transmission characteristics of the pilot signal used for channel estimation and the transmission characteristics of the signals of the link is taken into account when the signals of the link which are to be transmitted are produces by the transmitting station and/or when the received signals of the link are processed by the receiving station.
