Description

Transceiver station.

  The invention relates to a transmitting

  receiver for the transmission of information, constituted

  functional units arranged behind each other.

  the others in the flow of information, and to which is associated a common central

control and surveillance.

  For the transmission of electrical information

  that the state of the art has proposed a large number of transmission methods. Correspondingly,

  the variety of types of

  transceivers that enable these

  processes. Even in the case of transmitters-receivers

  using the same kind of operation

  and which are intended for a specific kind of information

  to be transmitted, for example speech, the functions

  gender-specific, which are carried out, may differ significantly

  who do not admit a reciprocal exchange of information.

  In order to reduce the technical means to put

  in the context of this multiplicity of

  types, it is known, for example from the document

  DE 34 15 008 A1, to implement a method of construction

  modular concept. In the context of this state of the art,

  that a fixed type of basic apparatus fixed and comprising a central control and monitoring unit is to be completed with other exchangeable function units to obtain a total apparatus in the form of drawers. In this way, we

  can achieve, by a corresponding combination of

  Functional units, with the central control and monitoring unit, a wide variety of different device types. In addition, it is possible, with the help of such

  modular construction method, to design, for example

  by implementing two and even a number of function units for signal modulation and for demodulation, transceivers

  which, at choice, can be switched from one mode of

  to another modulation mode, thus allowing flexibility in the exchange of information

  with other transceivers that are different

  between them from the point of view of the kind of modula-

  they use. But a very tight limit is placed on this flexibility by the number of drawers to be housed in a unit of apparatus, for dimensions

reasonable said drawers.

  Thus, the object of the invention is to indicate

  for a transceiver station of the type recalled at the beginning of this memo, another modular construction design that allows for the realization, with

  reasonable geometrical dimensions, units of

  with a very high flexibility for communication with transceiver

  are conceived differently from the functional point of view

  tional. Starting from a transceiver of the kind indicated at the beginning of this memoir, this problem is solved, according to the invention, by the means mentioned

  in the characterizing part of claim 1.

  The basic idea of the invention lies in the fact that it is extremely advantageous to achieve, with relatively small geometrical dimensions, two or more different transceiver stations, to obtain a single device, if the units which are mounted one after the other in such a unit of apparatus, are

  using signal processors to obtain

  multi-function units. The signal processor of such a multi-function unit performs, with one of these multi-function units, partial units associated with a single function, so that the mounting of the multi-function units, one after the other, others, is reduced to a montage of

  signal processors one after the other.

  The means to be implemented for the Central Control and Surveillance Unit are, from the point of view of its function, essentially limited, by the choice of a single function, to assemble, at the level of each

  multi-function units, a combination of

  hated of individual functions for the function

total.

  Advantageous embodiments of the invention

  jet according to claim 1, are indicated in the

other claims 2 to 9.

  The object of the invention will be explained in the

  description which follows and which is given as an example

  ple, with reference to the appended figures, in which

  the: Figure 1 represents the schematic diagram

other details.

  The block diagram according to FIG.

  feels a transceiver with a circuit

  input-output, BD-I / O, located on the operator side, three

  M! E multi-function tees that are mounted on

  behind each other, an EU-I input-output circuit

  I / O located next to the transmission path, a ZST central control and monitoring unit, which is associated with the MFE multi-function units, as well as a control panel BF which is provided for manual control and which is connected to the central control and monitoring unit ZST. The function unit

  multiple MFE which is provided on the input-circuit side

  BD-I / O output located on the operator side, is usually

  in the case of a transceiver, a CC codec, followed by a modem on the output side

  MM, corresponding to the third MFE multi-function unit.

  Since the information to be transmitted must be so that it can not be picked up by an unauthorized person, it is provided, as indicated in Figure 1 by a broken line, between the CC codec and the MM modem, as the third MFE multi-function unit, a coding or encryption unit. Each of these multi-function units MFE comprises at least two individual functions which are capable of being activated via the central control and monitoring unit ZST and which determine, according to the combination of the functions

  activated, the total function of the device.

  Figure 2 shows the constitution of principle

  of an MFE multi-function unit for two

  individual A unit with multiple functions

  However, MFE is not limited to two

  viduals that may be activated alternatively, but it may also include more than two such individual functions. The unit to

  multiple functions MFE includes a processor of

  which represents the entry and exit of the uni-

  multi-function MFE and which, in addition, is in

  liaison with the Central Control and Supervision Unit

  ZST launches. This signal processor SP represents, with regard to software and hardware, the central unit of the multifunction unit MFE, and operates, depending on the activation, either with the partial unit TE1 or with the unit partial TE2. Each of these two partial units TE1 and TE2 comprises, in a memory, the

  SW software which is particular for the indi-

  to be determined, and in another part of the

  cooked, the special HW material that is associated with the function

individual.

  The examples, shown in FIGS. 3 and 4, for input-output circuits, are envisaged for a transceiver station for the transmission of speech over lines. The input-output circuit BD-I / O, located on the operator side and which is shown in FIG. 3, shows a telephone receiver H which is connected, via an adaptation circuit.

  from the line G which represents a terminator, to the

  W for analog-to-digital or digital conversion

  America analog. The input-output circuit UE-I / O, located on the side of the transmission path, comprises, on the device side, again the converter W which is connected to

  the transmission line itself, through the

  of the line adaptation circuit G. The preferred embodiment, shown in FIG. 5, for a transceiver station operating with coding or encryption for the transmission of

  speech and data, uses circuits between

  3, and comprises, in accordance with FIG. 1, three MFE multi-function units mounted one behind the other and, in particular, a CC codec, a encoding or encryption unit SE and

  a modem MM. In this case, the codec includes the process

  SP1 as well as the partial units TE11 and TE22, the coding or encrypting unit SE, the

  signal processor SP2 as well as the partial units

  the TE21 and TE22, and the modem MM comprises the signal processor SP3 as well as the partial units TE31 and TE32. For data transmission, the CC codec and the MM modem can be dispensed with. For this purpose, the encryption or coding unit SE is arranged in the connection channel between two data interface units DI.

  which we can apply or from which we can

  lift the data at the connection terminals

who are free.

  For the transmission of voice information which must meet important requirements for

  regard to secrecy, as is, for example,

  In the case of an exchange of diplomatic and military information, the usual methods of jamming are not conceivable. The vocal signal

  analogue should rather be converted into the digital

  it must be encoded or encrypted, and the digital and encoded speech signal must be converted back into the analog plane after appropriate modulation with a carrier. In order to be satisfied, in

  this case, with the frequency band of telephone

  usual, it is necessary to reduce the information

  digitized speech, from the point of view of its

  of data, for example by reducing redundancy.

  For this purpose, and as indicated in the IEEE Transactions on Acoustics, Speech, and Signal Processing, Vol. ASSP-29, No. 1, February 1981, pages 13 to 23, there are several methods to vocoder. A preferred embodiment of the CC codec according to FIG. 5 thus consists in realizing the partial unit TE11, in cooperation with the signal processor SP1, in order to obtain a channel vocoder, and to realize the partial unit TE12, in cooperation with the SP1 signal processor to achieve a vocoder LPC, that is to say

linear prediction.

  Correspondingly, the encryption unit

  or SE coding can be performed for the functioning

  at the choice of the transceiver station, with two methods of encryption or coding which may be totally different from each other. For this purpose, the partial unit TE22 is designed, in cooperation with the signal processor SP2, for a first kind of

  encoding and decoding, and the TE2 partial unit is

  in cooperation with the signal processor SP2, for a second kind of coding and decoding. With the

  modem, it is finally possible to make two

  transferred different modulation-demodulation. In the preferred embodiment according to FIG. 5, the partial unit TE31 represents, with the signal processor SP3, a quadruple modulation by phase shift, 4 PSK, and the partial unit TE32, in cooperation with the signal processor SP3, represents a modulation

  amplitude in quadrature with 16 phases, 16 QAM.

  In this particular configuration, the transceiver unit represents a unit of apparatus which comprises at least two usual and different units of apparatus for speech coding or encryption, with a pronounced degree of secrecy, and in particular

  in the form of an extremely compact embodiment.

  Depending on which of the two different types of devices

  with which the transceiver must exchange information, the central control unit

  ZST service, a combination with a single function corresponding to

  of MYFE multi-function groups. In this

  Indeed, the Central Control and Surveillance Unit ZST

  takes an array of kinds of FT functions, indicated

  summarily in Figure 5, and which includes the combinations of

  sounds of control or command instructions for the signal processors of these multi-function units, which are associated with the various combinations

  functions of multi-function units

MFE pls.

  The setting for the desired type of operation can be made manually via the control panel BF. The kind of operation that is necessary to be able to carry out an exchange of information with a specific counter station,

  may be indicated, for example in the case of

  link, clearly to the operator of the remote station. In the exemplary embodiment according to FIG. 5,

  this is indicated by the fact that the circuits between

  output can be connected not only through

  multi-function units MFE, but also

  directly via line L,

  that is, with bridging of multi-function units

  ples. But it is also possible, within the framework of

  the establishment of a liaison with a distant post,

  first, to read the incoming signal from the remote station, using an analysis element provided in the modem MM, and then to obtain, automatically, using the central control unit and monitoring, the single function combination that is necessary for

the exchange of information.

  Transceiver stations that allow, with the choice and implementation of multi-function units, an exchange of information with transceiver stations that can not communicate with each other because of their different mode of operation,

  lend themselves, in an excellent way, to an exchange of information

  between networks or with networks that

  respectively comprise transmitting-receiving

  whose different mode of operation does not allow

  do not communicate directly between transceivers of different networks
