Description

The invention relates to communication technology, and more specifically to methods of transmitting and receiving information (PLI) through digital communication. The increase in the number of operators and subscribers, including cellular communications, exacerbates the problem of rational use of the frequency resource, which, in turn, requires further development and improvement of the PLI methods. The invention allows to increase the capacity of any existing system for transmitting and receiving information (SISP) for a given number of frequency bands allocated for operation or to provide a given capacity of SPSI with a smaller number of frequency bands, i.e. save frequency resource and increase the technical and economic efficiency of communication systems, taking into account all components that affect their full cost and technical performance.

A known method of transmitting and receiving information [Radio engineering: Encyclopedia / ed. Yu.L. Mazora et al. - M.: Dodeka-XXI Publishing House, 2002, pp. 63-64], the features of which are implemented, essentially, in all relevant methods and which is an analogue of the proposed technical solution. In this method, the source information is sequentially converted into a message in the physicoelectric information converter, encoded in an encoder, the carrier frequency is modulated with the encoded message and the signal is sent via the communication channel, the signal is received in the radio receiver, it is demodulated, decoded and the electrophysical inverse is performed transformation of the message of information into a consumer-friendly form.

respectively, in the processor of the nth decompression unit, the nth stream of M _n -ary symbols is simultaneously converted to K _n synchronized binary digital streams per cycle, which are delivered in an orderly manner, as in the aforementioned reading, to the outputs of the nth decompression unit, while the processor a compression unit has at least K _n inputs, which are said inputs of a compression unit, and at least one output, which is said output to said conversion system, and a processor of a decompression unit has at least one input, i which is considered to be the input of the decompression unit, and at least K _n outputs, which are the mentioned outputs of the decompression unit, and in the aforementioned conversion system, including, the stream of M _n -ary symbols is converted into a signal stream and the signal stream is converted back to the stream M _n - arny characters. In addition, in the method, at least information about the reference levels of M _n -ary signals is transmitted through at least one additional transmission channel.

In the current level of technology, no sources of information have been identified that would contain information about objects of the same purpose with the same set of distinctive features, which allows us to consider the PPI method of the present invention to be new and inventive.

The PPI method of the present invention can be embodied in a device, a block diagram of which is shown in the drawing.

Similarly, in brackets are numbers of digital streams of groups of information sources entering the multiple access unit on the transmitting side of the system and leaving the multiple access unit on the receiving side of the system.

In the inventive method, the PPI, in comparison with the well-known from the prior art, in the processor of the compaction unit, binary numbers K _{n of} synchronized binary digital streams are ordered at the same time per clock and converted to a stream of M _n -ary symbols and, accordingly, in the processor of the decompression unit, they simultaneously a stream of M _n -ary symbols in K _n synchronized binary digital streams that supply ordering, as in the aforementioned reading, to the outputs of the decompression unit. These actions allow using appropriate software to provide an increase in the technical and economic efficiency of known systems.

В процессоре 22 n-го блока уплотнения 5 упорядочение, например, последовательно от 1 до K_n, одновременно за такт считывают двоичные цифры К_n синхронизированных бинарных цифровых потоков, поступающих в процессор через K_n входов 24, и преобразуют их в n-й поток М_n-арных символов, где

В системе преобразования 8, в том числе, преобразуют поток уплотненных синхронизированных бинарных цифровых потоков в поток сигналов. Этот поток сигналов передают через передатчик 9 по крайней мере к одному приемнику 10 через канал передачи 11, совместимый с передаваемым сигналом (низкочастотным, высокочастотным или оптическим), и преобразуют в обратном порядке поток сигналов в поток уплотненных синхронизированных бинарных цифровых потоков. Далее этот поток подают с выхода 12 системы преобразования 8 на вход 13 по крайней мере одного n-го блока разуплотнения 14, соединенного со входом 26 процессора 23. В процессоре 23 n-го блока разуплотнения 14 одновременно за такт преобразуют n-й поток М_n-арных символов в К_n синхронизированных бинарных цифровых потоков, подаваемых с выходов 27 процессора, являющихся упомянутыми выходами 15 блока разуплотнения 14, в том числе, при необходимости, к своим блокам форматирования 16, не обязательно одинаковым с другими блоками форматирования. В блоках 16 цифровые потоки форматируют в информацию, которую направляют к соответствующим потребителям информации 2. При этом производят синхронизацию функционирования всех указанных блоков и упомянутой системы преобразования 8. При необходимости в системе преобразования 8 перед передатчиком 9 суммируют синхронизированные потоки сигналов в блоке множественного доступа 18, имеющем N входов 19 для доступа, в том числе, других групп источников информации, а после приемника 10 разделяют синхронизированные потоки сигналов в блоке множественного доступа 20, имеющем N выходов 21, в том числе, для других групп потребителей информации.The essence of the method is as follows. Information of every k-th, where

, from K _n information sources 1 from the n-th group of information sources, where

submit, including, if necessary, through its formatting unit 3, not necessarily the same with other formatting units, in which the information is formatted into a digital stream, to one of the K _n inputs 4 of the n-th block of the seal 5 connected to one of the inputs of the processor 22. In the processor 22 of the nth compaction block 5, ordering, for example, sequentially from 1 to K _n , at the same time read out the binary digits K _{n of the} synchronized binary digital streams entering the processor through K _n inputs 24 and convert them into nth stream M _n -ary symbol ov where

which is supplied from the output 25 of the processor, which is the mentioned output 6 of the seal unit 5, to the input 7 of the conversion system 8. In the conversion system 8, in particular, the stream of compressed synchronized binary digital streams is converted into a signal stream. This signal stream is transmitted through the transmitter 9 to at least one receiver 10 via a transmission channel 11 compatible with the transmitted signal (low-frequency, high-frequency or optical), and the signal stream is converted in the reverse order to a stream of compressed synchronized binary digital streams. Next, this stream is fed from the output 12 of the conversion system 8 to the input 13 of at least one nth decompression unit 14 connected to the input 26 of the processor 23. In the processor 23 of the nth decompression unit 14, the nth stream M _{n is} simultaneously converted per cycle -ary symbols in K _n synchronized binary digital streams supplied from the outputs of the processor 27, which are the mentioned outputs 15 of the decompression unit 14, including, if necessary, to their formatting units 16, not necessarily the same with other formatting units. In blocks 16, the digital streams are formatted into information that is sent to the corresponding consumers of information 2. In this case, the operation of all these blocks and the mentioned conversion system 8 are synchronized. If necessary, the synchronized signal streams in the multiple access unit 18 are summed in front of the transmitter 9, having N inputs 19 for access, including other groups of information sources, and after the receiver 10, synchronized signal streams in the block are divided multiple an access 20 having N outputs 21, including, for other groups of information consumers.

To increase the reliability of the system, it is advisable to transmit information about the reference, for example, single, levels of M _n -ary signals. It can be transmitted, for example, after several clock cycles on the main channel. However, in some cases it may be appropriate to transmit this and other information necessary for the organization of the system through an additional channel. Therefore, at least information about the reference levels of M _n -ary signals is transmitted through at least one additional transmission channel.

In the processor of the compaction unit, at each clock cycle (i.e., simultaneously), the ordering reads information coming from K _n sources. Note that each information channel can carry information of any kind, for example, encoded by any code or a mixture of codes. The read information is converted into a stream of M _n -ary symbols. In the processor of the decompression unit, at the same time, the stream of M _n -ary symbols is restored (decompressed) into K _n synchronized binary digital streams and their ordering, as when reading the compaction unit in the processor, is transferred to K _n consumers in a form convenient for them. The proposed method belongs to the number of combinational densification and channel separation methods [Kharkevich A.A. Essays on the general theory of communication. M.: Gostekhizdat, 1955, §53].

When implementing the method, all of the SDSI blocks can be made the same as in other systems of the same purpose. The timing and synchronization issues of the transmitting and receiving sides are solved by any means well known in the art, for example, in the same way as in the prototype. In some cases, it is sufficient to use one decompression unit, from each output of which information is sent to the corresponding consumer of information. In some cases, two or more, up to K _n , decompression blocks can be used. For example, in cellular communications, each mobile station includes a decompression unit. From a stream of M _n -ary symbols entering this block, a binary digital stream is allocated that is currently addressed only to this consumer. Thus, in cellular communications, the signal flow is delivered to all consumers, and the decompression procedure is performed by each final destination.

Efficient computational algorithms, including well-known ones, are used for compaction and decompression (restoration of initial information), which facilitates their hardware-software implementation.

This simplest possible example of the use of the proposed method of PLI clearly shows the possibility of simultaneous transmission and reception of three streams of text information on one channel, which increases the efficiency of using the frequency resource.

The present invention is useful in that it can be practically applied for the development and improvement of any digital communication system with any organization of its work, for example, already using well-known multiple access methods (for example, with frequency, time, code, spatial and polarization separation) and known signal processing methods, including, for example, for all known cellular standards.

Industrial applicability. The present invention can be applied in SISP using low-frequency, high-frequency and optical signals in any communication systems. The PPI method according to this invention allows efficient use of the frequency resource and can work simultaneously with a large number of heterogeneous information.

The analysis made it possible to establish: analogues with a set of features that are identical to all the features of the claimed technical solution are absent, which indicates the compliance of the proposed method with the condition of "novelty".

The search results for known solutions in the field of PPI methods in order to identify signs that match the distinctive features of the prototype of the claimed method showed that they do not follow explicitly from the prior art. Therefore, the claimed invention meets the condition of patentability "inventive step".
