摘要： Disclosed is a radio reception system (1) comprising two receive antennas (11, 12), two receivers (13, 14), and a transformer (15) that is used for feeding radio signals of both antennas (11, 12) to each receiver (13, 14) and is provided with a first (151) and a second winding (152). The inventive radio reception system (1) is characterized in that the two receive antennas (11, 12) are connected to the terminals (1511, 1513) of the first winding (151) while a first (13) of the two receivers (13, 14) is connected to a central tap (1512) of the first winding (151) and a second (14) of the two receivers (13, 14) is connected to a terminal (1521) of the second winding (152). Said radio reception system encompassing the features of the independent claim represents an advantageous alternative to the radio reception system described in patent number DE 101 30 234 A1.

摘要： An arrangement for connecting at least two receivers to a common antenna is disclosed, whereby antenna signal lines are fed to the receivers, is characterised in that the input impedances for the at least two receivers are only matched to the impedance of the supplied antenna signal lines in the narrow band of the region of the current receiver frequencies. An antenna signal splitter is further disclosed and also a method for control of the receiver frequencies of at least two receivers, connected to a common receiver antenna, which is characterised in that the receiver frequencies for the at least two receivers are set such that they have a pre-determined minimum frequency difference from each other. The invention permits a reduction in an antenna signal damping in an antenna signal splitter for multi-receiver systems so long as the receivers are matched to differing receiver frequencies.

摘要： The invention relates to a playback device for audio signals that are transmitted over potentially disturbed channels. Said playback device is equipped with a unit (43) for detecting a degree of disturbance of the audio signals, with a unit (45) for reducing high-frequency portions of the audio signals according to the degree of disturbance, and with a sound influencing unit (46) for amplifying the audio signals in a frequency-selective manner. The reducing unit (45) for reducing high-frequency portions of the audio signals is additionally configured according to a frequency-selective audio signal amplification that is preset by the sound influencing unit (46). The inventive playback device makes it possible to achieve a level reduction, which is dependent on disturbances and which is independent of a sound presetting.

摘要： The invention relates to a radio receiver system comprising a plurality of reception antennae (111-119) and a plurality of receivers (191-199) that is characterized in that every one of the plurality of receivers is supplied with antenna signals of a greater part of the plurality of reception antennae. The inventive system allows for a more flexible interconnection of the plurality of reception antennae with the plurality of receivers depending on the selected reception strategy. The operability of the entire system can be substantially maintained in the event of a defect or even failure of individual or several reception antennae.

摘要： The invention relates to a method for controlling power gain for a send-signal of a radio device. The emission power is increased to a predetermined level along a pre-set characteristic curve at the beginning of a send-signal. At the end of the send-signal, the predetermined level along the pre-set characteristic curve is lowered. Power gain is controlled accordingly by means of a control signal (8, 9). A reference control signal (5) is used for the rising and descending edges of the control signal (8, 9). The control signal (8, 9) is restricted to a preset maximum value (6, 7).

摘要： The invention relates to a radio apparatus (95), particularly for use in mobile telephony, which allows for a presettable optimal adjustment of signal reception. Said radio apparatus (95) comprises a receiver element (1) and an evaluation unit (5), which unit adjusts the sensitivity and/or noise immunity of the receiver element (1) in accordance with a presettable signal reception quality and actual signal reception. The evaluation unit (5) increases the sensitivity and/or noise immunity of the receiver element (1) in case of faulty signal reception and lowers its sensitivity and/or noise immunity if signal reception has been fault-free for a predetermined period.
