Definitions

  • the reception with two antennas is shown to illustrate the invention, wherein the method can be used in principle for more than two antennas.
  • Each receiving antenna (not shown here) is assigned its own tuner 1, 3. It should be carried out a switching of the received signal on the IF (intermediate frequency) level, it is irrelevant whether it is a first or further IF.
  • the tuners 1, 3 are each assigned a measuring device 2, 4 and a downstream switching device 5.
  • the switching device 5 in turn is followed by a demodulation circuit 6, the output signals of a reproducing device, not shown here for the reproduction of the received and processed high-frequency signals (RF signals) are supplied.
  • the switching can take place without the involvement of a control unit.
  • the information obtained by the measuring devices 2, 4 and 6 are further processed directly in a decision-making arrangement 8 and guided to the switching device 5.

Abstract

L'invention concerne une diversité d'antennes dans laquelle des signaux haute fréquence (signaux HF) reçus via plusieurs antennes sont envoyés respectivement à un syntoniseur (1, 3). L'invention est caractérisée en ce que les signaux de sortie de fréquence intermédiaire (signaux ZF) du syntoniseur (1, 3) sont envoyés à un dispositif de commutation (5) qui connecte respectivement un signal ZF à un dispositif de démodulation monté à la suite (6).
