Abstract

What is described here is an array for multi-channel signal transmission between mobile units, consisting of at least one first transmitter/receiver unit that is coupled to at least one second transmitter/receiver unit via transmitting means.

The inventive array is characterized by the provision that in said first and said second transmitter/receiver units respective mutually tuned filter banks are provided that filter predetermined characteristic spectral fractions out of the signals to be transmitted, that combine these signals to form a cumulative signal in the case of transmission, that pass on these signals to additionally provided signal regenerators in the case of reception for regenerating the original signal, and that moreover directional switches are provided that separate the signals of the transmission and reception path from each other or that combine transmitted and received signals in such a way that they will be transmitted via a common transmitting means.

Claims

1. Array for multi-channel transmission of signals between mobile units, consisting of at least one first transmitter/receiver unit (1) that is coupled to at least one second transmitter/receiver unit (3) via transmitting means (2), wherein respective filter banks (4, 6, 12, 19) are provided in said first and second transmitter/receiver units, which filter banks filter predetermined spectral fractions out of the signals to be transmitted, combine these signals to form a cumulative signal (13, 13b) in the case of transmission, and pass on these signals to additionally provided signal regenerators (7a, 7b, 7c, 7d, 17a, 17b, 17c, 17d) in the case of reception for regenerating the original signal, characterized in that directional switches (9, 10) are provided that separate the signals of the transmission and reception path from each other or combine transmitted and received signals in such a way that they will be transmitted via a common transmitting means, and that said filter banks are so designed that they filter characteristic spectral fractions out of the signals to be transmitted.

2. Array according to claim 1,

characterized in that in the case of an additional transmission of exclusively unidirectional signals merely the respective first transmitter/receiver unit (1) comprises a filter bank (4) that filters characteristic spectral ranges out of the individual signals to be transmitted and combines them to form a cumulative signal (13) that is transmitted directly, without directional switches, to said transmitting means (2), and that additionally a second transmitter/receiver unit (3) is configured exclusively for reception, which filters the signals of said transmitting means out by means of a second filter bank (6) and communicates them to additionally provided signal regenerators (7a, 7b, 7c, 7d) for signal processing.

3. Array according to any of the claims 1 or 2,

characterized in that in the case of transmission of signals limited in terms of bandwidth, which may be detected almost over their entire spectrum, the signal path of these signals is provided exclusively with a filter bank for reception, without a joining signal regenerator.

4. Array according to any of the claims 1 to 3,

characterized in that said directional switch presents, in its turn, frequency-selective characteristics.
