摘要： A radio transmission system is disclosed for operating in a multipath transmission environment having improved reception, and in the case of bi-directional systems, also improved transmission. This is achieved by using at least two reception beams, corresponding to one fixed reception beam and one scanning reception beam, and by continuously evaluating the quality of these beams as to their signal-to-noise-and-interference ratios or bit-error-rates (BERs). The best beam is dynamically chosen to be the fixed beam. Alternatively, the fixed beam is updated with the best beam acquired by the scanning beam as compared to the current fixed beam. In a bi-directional system, the receiving radio apparatus applies the direction of the best reception beam for transmission to the opposite radio apparatus.

摘要： A radio transmission system comprises a phased-array radio apparatus for optimizing reception in a multipath transmission environment. In the phased-array radio apparatus, phase shifting is performed after down-conversion of received RF signals. Phase control and beam-forming are simple. By applying a zero-IF or low-IF receiver structure, the complete structure can easily be fully integrated.

摘要： The invention relates to an antenna diversity comprising a first and a second antenna element where the first antenna element is operated in an active mode whereas the second antenna element is operated in a parasitic mode. The present invention minimizes the amount of mismatch while still being able to maximize a predetermined signal quality criterion for the electromagnetic signal on the active path between the first antenna element and the transceiver. By providing a pre-selection unit 130 as well as a selection unit 140 for selecting an optimal adjustable impedance connected to the second antenna ensuring that the amount of said mismatch is below a predetermined threshold value and that simultaneously a predetermined quality criterion for the transceived electromagnetic signal is fulfilled best within the range determined by the allowable mismatch. The invention further relates to a method for operating such an antenna diversity.

摘要： For audio and/or video or control signal transmission between two rooms in, for example, a house, inductive and/or capacitive transmitters and receivers are used which are installed on opposite sides of the partition or wall that separates the rooms. The signals to be transmitted may be applied or tapped from the transmitter/receiver by cables or by infrared transceiving diodes. The transmitter and receiver consist of, for example, two metal plates or two coils installed substantially opposite each other on opposing sides of the wall.
