    摘要: A device and a method for the transmission or storage of data optimizing the use of the pass-band. Also, a method for transmission by phase modulation. In order to obtain high data throughput rates, the synchronization of a transmission clock with the reception clocks is used. This synchronization is gotten, for example, by transmission of a pseudo-random code and by the convolution or correlation of the received signals with the pseudo-random code. The invention also enables the elimination of multiple echoes by computation. The invention can be applied chiefly to the transmission of radio programs, television broadcasts or digital data.

    摘要: In a method and a device for correcting a frequency offset between a receive signal and a reference signal, the receive signal, being fed to a frequency converter which also receives a conversion signal in order to produce a transposed signal, the conversion signal is produced by a local oscillator in response to a control signal. The device initializes the control signal according to the reference signal. An estimator receives the transposed signal and the control signal and produces repetitively an estimate of the frequency offset comprising the sum of a correction value and an adjustment value respectively greater than and less than a predetermined correction threshold. The control signal is modified in response to the correction value. The transposed signal is connected using at least one of the successive estimates.

    摘要: A dual mode portable digital radio transceiver for communicating via a terrestrial network (first mode) and via a satellite network (second mode) synthesizes a modulation first frequency for modulation of signals transmitted in both modes and a conversion second frequency for demodulation of signals received in the two modes. It divides the conversion second frequency supplying a conversion third frequency for demodulation of signals received in one of the modes using a signal receive frequency band far away from the other frequency bands used. It is therefore possible, using a single synthesized pure carrier, to carry out direct conversion in a first mode and intermediate frequency conversion followed by the same direct conversion in the second mode.

    摘要: A digital filter having parallel paths with a plurality of transverse filters in the paths. The period of treating the digital information of N connections at the output of a circuit for calculating the discrete Fourier transform on 2N points. The output of the transverse filter is fed to a circuit for calculating the inverse Fourier transform. These two circuits permit the transverse filters to function in each path with a data period of N. The filter will find particular application in convolvers, courolaters, and for circuits for the compression of digital pulses. The filter lends itself to application, particularly in radar, sonar, telecommunications, and in sound and imaging systems.

    摘要: An apparatus and method for reducing the power of active jamming signals received by the sidelobes of a radar antenna. A known method includes providing a radar with a main antenna and N auxiliary antennas, each antenna being associated with a corresponding processing channel. The signals received by the N antennas are each given a weighting coefficient corresponding to jamming on that channel. The N signals are then combined to form a weighted linear combination which is subtracted from the main channel signal to provide a signal with reduced jamming. The present invention provides apparatus and method for reducing clutter signals (such as fixed echoes and thermal noise) from each of the signals received in the N channels, thus producing very accurate weighting coefficients thereby allowing jamming power to be further reduced. Apparatus and method are provided for carrying out moving target indication (MTI) on all channels, determining the jammed range cells by comparing the main channel signal with the auxiliary channel signals and validating these signals with respect to thermal noise, determining the weighting coefficients from information derived from a given number of jammed range cells (preferably those grouped together at the end of recurrence), forming the weighted linear combination from only those signals which are, in fact, jammed, and subtracting the weighted linear combination from the main channel signal.

    摘要: A multimode radio communication terminal includes a tunable source of transmit and/or receive local oscillator signals for transmitting and/or receiving channels of different frequency bands in at least two radio communication systems. The terminal includes, downstream of the tunable source, a switchable frequency changer implementing a fixed frequency change and selectively insertable so that, the source responding directly to the requirements of one radio communication system, insertion of the frequency changer renders it capable of responding to the requirements of another radio communication system using different frequency bands. This is achieved by virtue of a particular change to the frequency produced by the tunable source, effected by the frequency changer.
