Description

Verfahren zur drahtlosen Nachrichtenübermittlung Bei der drahtlosen Nachrichtenübermittlung treten häufig verschiedene Störungen auf, die eine Verbindung zwischen den einzelnen Stationen für kürzere oder längere Zeit unmöglich machen. Es sind dies entweder atmosphärische Störungen, die bekanntlich senkrecht einfallen, und außerdem treten Störungen durch fremde Sender und vor allen Dingen Fadingserscheinungen auf. Man hat zu deren Beseitigung bzw. Verminderung bereits eine Reihe von Mitteln angegeben, wie z. B. gerichtete Antennen, besondere Empfängerschaltungen mit Sperr- und Siebkreisen zu verwenden. Man hat versucht, eine Störbefreiung dadurch zu erzielen, daß dieselbe Nachricht gleichzeitig auf zwei verschiedenen, weit voneinander abliegenden Wellen zur Ausstrahlung gebracht wird. Ferner hat man vorgeschlagen, die Welle in einem bestimmten Polarisationszustand auszusenden und empfangsseitig Einrichtungen zu verwenden, die nur Wellen bestimmter Polarisation aufnehmen.Method of wireless messaging In the case of wireless Messaging often encounters various glitches that affect a connection between the individual stations impossible for a shorter or longer period of time. These are either atmospheric disturbances, which are known to occur perpendicularly, and there is also interference from external transmitters and, above all, fading phenomena on. A number of means are already available for eliminating or reducing them specified, such as B. directional antennas, special receiver circuits with blocking and sieve circles to be used. Attempts have been made to eliminate interference by that the same message is sent to two different, widely separated messages at the same time Waves is made to radiate. It has also been proposed that the shaft in to emit a certain polarization state and devices on the receiving side to use, which only pick up waves of a certain polarization.

Gegenstand der Erfindung ist es, die zu übermittelnden Nachrichten nicht wie bisher auf verschiedenen Wellen zur Ausstrahlung zu bringen, sondern auf derselben Welle, jedoch unter Verwendung verschiedener Polarisationszustände.The object of the invention is the messages to be transmitted not to make it radiate on different waves as before, but on same wave, but using different polarization states.

Zur Durchführung des Erfindungsgedankens werden beispielsweise am Sendeort zwei oder mehrere Wellen der gleichen Wellenlänge, jedoch verschiedener Polarisation, beispielsweise die eine horizontal, die andere vertikal polarisiert, zur Übermittlung zweier verschiedener Zeichen verwendet. Auf der Empfangsseite werden die Wellen durch Empfangsgebilde aufgenommen, die für die betreffende Polarisation besonders aufnahmefähig sind.To implement the inventive concept, for example, on Transmission location two or more waves of the same wavelength, but different Polarization, for example one polarized horizontally, the other vertically, used to transmit two different characters. Be on the receiving side the waves are absorbed by receiving structures that are responsible for the polarization in question are particularly receptive.

Gemäß der weiteren Erfindung ist es möglich, eine Geheimhaltung der übermittelten Nachrichten und eine Aufnahme durch unberechtigte Dritte dadurch zu verhindern, daß die Polarisationszustände während des Betriebes geändert werden. Auch ist es möglich, die Polarisation am Sender und Empfänger stetig veränderlich zu gestalten, beispielsweise durch Verwendung drehbarer Dipole, drehbarer Rahmen u. dgl., um dauernd eine Anpassung an die günstigste Einstellung, beispielsweise Nachregulierung bei Änderung der Polarisation der einfallenden Wellen auf den günstigsten Wert aufrechtzuerhalten. Zur Verwendung können alle an sich bekannten Mittel zur Ausstrahlung bzw. zum Empfang Anwendung finden, wie insbesondere offene Antennen (Dipole) und Schleifen oder auch geeignete Antennenkombinationen.According to the further invention, it is possible to keep the transmitted messages and recording by unauthorized third parties prevent the polarization states from being changed during operation. It is also possible to continuously change the polarization on the transmitter and receiver to design, for example by using rotatable dipoles, rotatable frames and the like. To constantly adapt to the most favorable setting, for example Readjustment when changing the polarization of the incident waves to the most favorable Maintain value. All means known per se can be used for Broadcasting or receiving applications, such as open antennas in particular (Dipoles) and loops or suitable antenna combinations.
