Abstract: A demodulation circuit for demodulating a received signal including carriers in quadrature modulated by digital signals and/or in which the processing is performed on two carriers in quadrature. The circuit includes a demodulator, an analog-to-digital converter, a correcting circuit, and a derotator. The correcting circuit provides signals to the derotator based on the derotator output signals and on signals provided by the analog-to-digital converter.

Abstract: A process for receiving a composite signal transmitted via a nonlinear data transmission channel comprising a first signal UL and a second signal LL. The process comprises the following: demodulating and decoding said first signal UL by means of a first demodulation and decoding chain in order to regenerate said first information UL; recoding and shaping to produce a continuous time waveform; applying a nonlinearity function based on a set of coefficients updated according to an adaptive correlation calculation process to said continuous time waveform; subtracting the result of said nonlinearity function from said composite signal in order to generate a result E; and demodulating and decoding said result E by means of a second demodulation and decoding chain in order to regenerate said second information LL.

Abstract: The present invention relates to a digital filter for a phase-locked loop receiving at least one input signal having a predetermined period, including an element of accumulation of frequency values receiving the output of a phase detector; and an element of accumulation of phase values receiving a weighted sum of the output of the phase detector and of the content of the element of accumulation of frequency values. Each of the accumulation elements includes several frequency or phase value storage locations, circuitry being provided for successively making operative the storage locations in the phase-locked loop during a period of the input signal.

Abstract: A device for two-way digital transmission on a bus having at least one two-way line. The device includes a first pulling device for pulling a first section of the line to a first logic level, a second pulling device for pulling a second section of the line to the first logic level, and at least one two-way repeater that is connected between the first section and the second section. The repeater includes a third pulling device for pulling the first section of the line to a second logic level, a fourth pulling device for pulling the second section of the line to the second logic level, and a logic circuit that prevents the third and fourth pulling devices from being simultaneously active. In one preferred embodiment, at least one electronic circuit is connected to the first section of the line and at least one other electronic circuit is connected to the second section of the line. In another preferred embodiment, the repeater also includes a conditional circuit that is controlled by an electronic circuits connected to the first section. The conditional circuit selectively enables or prevents transmission between the first and second sections of the line.

Abstract: A method for detecting a locked condition of a demodulator of at least one signal that may have discrete levels defining a constellation of nominal points in a plane. The method includes the steps of defining reference areas about the nominal points, a reference area being separated from another by a band or an angular sector crossing the origin of the constellation plane, and indicating a locked condition if the ratio of points occurring in the reference areas is above the probability for points to occur in the reference area, when the demodulator is wrongly adjusted.
