Information transmission system

The invention relates to an information transmission system which exhibits a digital signal channel for transmitting a digital signal and an analog signal channel for transmitting an analog signal. The digital signal is transmitted by modulating a carrier oscillation in accordance with a phase-shift-keying method. The analog signal is transmitted by frequency modulation of the carrier oscillation. In the receiving station, the carrier oscillation required for coherent demodulation is generated in a carrier generator. It is synchronised by a synchronisation signal generated from the modulated carrier oscillation. The frequency modulation produces phases errors which can cause bit errors in the digital signal. When the analog signal has high amplitudes, the synchronisation stops, which can case the transmission of the digital signal to be interrupted. According to the invention, an interference-free transmission of the digital signal is achieved even with amplitudes of the analog signal of ...

The service channel signals are frequency modulated and the frequency modulated signal is caused to pulse width modulate pulses forming the regular data signal. The pulse width modulation is done in two different ways, depending on whether the data signal is an RZ-coded bit flow or an NRZ-coded bit flow.

Improvements in multiplex electrical signalling

... 203,711. Day, A. van T. Sept J.1. 1922, [Convention date]. Itlultiplex signalling; secret and selective signalling; thermionic amplifiers and modulating systems.-Signalling or distant control is effected by radiation or along wire conductors by a method in which a carrier wave is modulated by a sub-wave, which is itself modulated by a second subwave, and so on, the last sub-wave being modulated by a voice current or other signal. By selecting combinations of two or more of the sub-waves, a large number of channels may be provided for sending independent messages over the same aerial or conductor. The modulating-apparatus is of the kind in which the pure input waves are balanced out in the output circuit, and only the side-bands, or the sum and difference frequencies, are permitted to pass. At the receiver, the waves are passed through separate and successive de-modulators or detectors, each of which is supplied locally with a wave of the same frequency as was supplied at the corresponding ...

ARRANGEMENTS FOR TRANSMITTING ELECTRICAL SIGNALS

Demodulators of frequency modulation receivers

... 1,009,646. Frequency modulation. WESTERN ELECTRIC CO. Inc. April 18, 1962 [April 25, 1961], No. 15004/62. Heading H3R. In a frequency modulation receiver with feedback of the discriminator output to frequency modulate a local oscillator and thereby reduce the I.F. frequency swing, the I.F. pass-band is given a single tuned circuit characteristic and a second filter between the discriminator and oscillator passes the modulation signal bandwidth. The I.F. filter pass-band, although narrow, is made as wide as possible consistent with its not creating a carrier-to-noise power threshold for the receiver in receiving a weak carrier and so that a second threshold is produced with the feed-back loop closed which governs the performance, this threshold being due to higher order sidebands of the modulated local oscillator being produced when a large modulation index is used. According to the invention, the feed-back filter is adjusted in pass-band to ensure that the second threshold is reduced to ...

One or more connections may couple each leaf node to the hub node, whereby each connection may include one or more spans or segments of optical fibers, optical amplifiers, optical splitters/combiners, and optical add/drop multiplexer, for example. Optical subcarriers may be transmitted over such connections, each carrying a data stream. The subcarriers may be generated by a combination of a laser and a modulator, such that multiple lasers and modulators are not required, and costs may be reduced. As the bandwidth or capacity requirements of the leaf nodes change, the number of subcarriers, and thus the amount of data provided to each node, may be changed accordingly. Each subcarrier within a dedicated group of subcarriers may carry OAM or control channel information to a corresponding leaf node, and such information may be used by the leaf node to configure the leaf node to have a desired bandwidth or capacity. 1. An apparatus , comprising:a first digital signal processor operable to supply first electrical signals during a first time interval and second electrical signals during a second time interval;a first laser operable to supply a first optical signal;a first modulator operable to modulate the first optical signal to provide a first plurality of optical subcarriers during the first time interval and a second plurality of optical subcarriers during the second time interval, the first plurality of optical subcarriers carrying first data and the second plurality of optical subcarriers carrying second data;a second digital signal processor operable to supply third electrical signals during the first time ...

Method of controlling transmission, transmitting device and receiving device for wireless communication system

FIELD: radio engineering, communication. SUBSTANCE: in a wireless communication system, a transmitting device (1) transmits for each of a plurality of data streams a data block with associated identification information of the data block, which does not conflict between data streams. A receiving device (2) performs retransmission synthesis for an already received data block and a retransmitted data block to which the same data block identification information is associated, based on data block identification information associated with the received data block. Furthermore, if the number of streams transmitted between the transmitting device (1) and the receiving device (2) varies (drops), the data block matching property which is the objective of the retransmission synthesis, can be preserved and communication can continue in normal mode. EFFECT: invention enables to avoid improper retransmission of a data block from a transmitting device and improper synthesis of a data block in a receiving device. 2 cl, 32 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (51) МПК H04J 99/00 (11) (13) 2 562 960 C1 (2009.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ 2014123670/07, 10.06.2014 (24) Дата начала отсчета срока действия патента: 27.10.2006 Приоритет(ы): (30) Конвенционный приоритет: 25.04.2011 (73) Патентообладатель(и): ФУДЗИЦУ ЛИМИТЕД (JP) C 1 2 5 6 2 9 6 0 R U Адрес для переписки: 129090, Москва, ул.
