摘要： A system for diversity processing two signals (INPUT 1 , INPUT 2 ) transmitted and/or received via two diversity antennas (1, 2) includes at least four respective propagation paths coupling the signals to the two diversity antennas (1, 2). Diversity processing is primarily in the form of decorrelation achieved by means of time variable delay elements (161 to 164; 261 to 264; 1261 to 1264) that apply time variable delays to the signals propagating over at least two of the propagation paths in the system. The related processing may take place either at RF or IF, or at baseband, whereby the time variable delays are applied by subjecting the baseband signals to multiplication by a complex signal.

摘要： A differential delay element (10) for use e.g. in selectively delaying RF signals in telecommunication systems includes a first microstrip circuit (12) and a second microstrip circuit (14) arranged side-by-side in a facing relationship. The first microstrip circuit (12) defines a first delayed travel path for a first signal from a first input port (IN1 ) to a first output port (OUT1 ) and the second microstrip circuit (14) defines a second delayed travel path for a second signal from a second input port (IN2) to a second output port (OUT2). A perturber (18) is arranged between the first (12) and second (14) microstrip circuits, displaceable (20) towards and away from the first (12) and second (14) microstrip circuits, so that when the distance of the perturber (18) to one (12 resp. 14) of the microstrip circuits increases, the distance of the perturber (18) to the other (14 resp. 12) of the microstrip circuits decreases and viceversa. The position of the perturber (18) between the first (12) and second (14) microstrip circuits defines the differential delay, namely the difference (Δτ=τ1-τ2) between the times (τ1, τ2) experienced by the two signals in travelling their travel paths through the delay device (10).

摘要： A method of transmitting signals from a base station towards user terminals in a cellular communication system. The method includes generating (18) a plurality of diversity signals, wherein at least one of said diversity signals is subjected to a selectively variable RF phase shift (20). Specifically, a set of radio link quality indicators (KPI) is determined at the base station, wherein each radio link quality indicator (KPI) is representative for the quality of the radio link between the base station and a respective one of the user terminals (UE). The set of radio link quality indicators (KPI) is used to generate an aggregated radio quality indicator, which in turn is used to selectively vary the variable RF phase shift. For example, the phase shift may be selected, which optimizes the aggregated radio quality indicator.
