摘要： A reflector antenna, in particular for the reception and/or transmission of signals from and/or to satellites. The reflector antenna according to the invention comprises a reflector arrangement for focusing antenna radiation in a focal plane together with an antenna array arranged in the focal plane, or in the vicinity of the focal plane, with a plurality of antenna elements. A control device is provided with a beamforming means. Through the control device, sub-arrays, comprising one or a plurality of antenna elements of the antenna array for the reception and/or transmission of antenna radiation, can be activated and deactivated. In the operation of the reflector antenna, a radiation lobe pattern is formed by means of the beamforming means for the reception and/or transmission of antenna radiation for a particular activated sub-array.

摘要： A process for transmitting digital signals, in which the digital data are coded differentially in symbols of a symbol period T.sub.s (2.1, 2.2), the symbols transmitted with the Q component being delayed by T.sub.s /2, relative to those of the I component, to achieve a time-staggering. A cross interference of the I and Q components, occurring on the receiver end and caused by the differential coding nd the time staggering, is resolved with a trellis decoder (10), for example. As a result, a differential offset QPSK process achieved on this basis combines the advantages of DQPSK and OQPSK procedures.
