Embodiment Construction

[0063] A method for transmitting digital messages is implemented as follows.

[0064] An operation generating matrix G having k rows (k+1) columns is formed using the operation g on its diagonal 0 and has the operation g elsewhere 1 a k×k matrix, and use the operation g that is added to the k×k matrix from the right and corresponds to each position 0 or operation g 2 Additional columns of the sequence to generate. It is also possible to use an operationally generated matrix generated by rearranging its rows and / or columns using said operationally generated matrix. The resulting operation-generating matrix is ​​not a matrix of numbers, as usual matrices, but a matrix of records which are delivered to generate the corresponding operation when the corresponding elements of the operation-generating matrix are activated.

[0065] The operation of adding an additional column is generated with the purpose of introducing a check element in the transmitted message for finding error...

Abstract

The invention relates to telecommunications, in particular to methods and means for transmitting digital messages and can be used for transmitting information through wire channels and telecommunication channels using electromagnetic waves. The use of said channels is simplified by excluding multiplication and division operators from the coding and a decoding process. Said invention makes it possible to transmit any messages from elements of Abelian group including code words whose elements are matrixes, polynomials, numbers of mixed-base notation and nonpositional notation. The inventive encoder comprises a driver clock (7), a function g<2> calculator (8), a pulse generator (9) having recurrent frequency of f(k+1) / k, a pulse recurrent frequency doubler (10), a ring counter (11) up to k, an adder-accumulator of elements of Abelian group (12), a key (13), a ring counter (14) up to (2k+1), an AND component (15), a main memory unit (16), a key (17), a trigger (18), a main memory unit (19) and a ring counter (20) up to (k+1). The inventive decoder comprises a driver clock (21), an adder-accumulator of elements of Abelin groupoid (21), a pulse generator (23) having recurrent frequency of fk(k+1) / k, a pulse recurrent frequency doubler (24), a ring counter (25) up to (k+1), a key (26), a main memory unit (27), a key (28), an AND component (29), a ring counter up to [2(k+1)+1] (30), an identification unit provided with a single element of Abelian group (31), a trigger (32), a main memory unit (33) a key (34), a ring counter (35) up to k.

Description

technical field [0001] The present invention relates to telecommunications, and in particular to methods and apparatus for transmitting digital messages, and may be used to transmit information over wired channels and over wireless telecommunication channels using electromagnetic waves. Background technique [0002] A method for transmitting digital messages containing additive Abelian group elements is known. The method includes the steps of encoding, modulating and transmitting a digital message in a communication channel, and demodulating and decoding the received signal [1]. [0003] A known system for transmitting digital messages containing additional elements of an Abelian group comprising an encoder, modulator and transmitter connected in series at the transmitting end, and a receiver, demodulator and decoder connected in series at the receiving end [1]. [0004] The known methods and systems are rather complicated to implement, since they use four arithmetic opera...
