Abstract: A controllable pulse generator generates the pulses of the signal which are respectively contained in successive time windows, and a control device formulates a control signal for the generator including, for each pulse, an indication of its position in the corresponding window. The control device includes a processor to deliver for each time window, at a delivery frequency Fe greater than the pulse repetition frequency, successive groups of N bits together defining a digital cue of position of a pulse inside the window. Also, a converter converts this digital position cue into the control signal temporally spread over the length (T) of the window and including the indication of position at an instant corresponding to the digital position cue. This makes it possible to position the pulse inside its window with a temporal precision equal to 1/N.Fe.

Abstract: AC/DC converters comprise rectifiers for rectifying AC signals into DC signals. By providing these AC/DC converters with voltage dividing capacitors located between converter-input, a resistor, added to voltage dividing capacitor for filtering peak signals, and a rectifier, the rectifier can be better integrated, as it no longer receives the entire input voltage present at the converter-input of the AC/DC converter, without a conventional transformer comprising an iron core and windings being required. Such an AC/DC-converter is small sized, of light-weight and low costly made. Preferably, the converter-input is symmetric, the rectifier comprises two diodes and two transistors and a zero-cross detector for switching the transistors, the AC/DC converter comprises a down-converter located between the rectifier and converter-output for further down-converting purposes and comprising an inductor and a regulator for regulating inductor/capacitor-energies, with buffer capacitors being present in parallel to the down-converter for stabilising purposes, to get a transformerless wall plug adapter.

Abstract: An incident pulse signal of the ultra wideband type conveys digital information that is coded using pulses having a known theoretical shape. A decoding device includes an input for receiving the incident signal, and for delivering a base signal. A comparator receives the base signal and delivers an intermediate signal representative of the sign of the base signal with respect to a reference. A sampling circuit samples the intermediate signal for delivering a digital signal. A digital processing circuit correlates the digital signal with a reference correlation signal corresponding to a theoretical base signal arising from the reception of a theoretical pulse having the known theoretical shape.

Abstract: First estimations of the fading coefficients of a multi-path transmission channel are carried out in the sense of maximum likelihood. Sets of Wiener filter coefficients are stored according to predetermined speeds of movement of the mobile terminal and predetermined power levels of the signal. The real speed of the mobile terminal is estimated and the power of the signal for each path is measured. From this, a set of Wiener filter coefficients is derived with which the first estimations are filtered to obtain the final estimation of the fading coefficients.

Abstract: A rake receiver uses a delayed version of the received sequence and a delayed version of a scrambling code. The flexible hardware structure of the time-aligning and descrambling unit includes at least two delay chains and one multiplier. By controlling two multiplexers, the delayed versions of the received sequence can be multiplied with an arbitrary scrambling code having an arbitrary phase. During one chip period, one multiplication is performed for each path to be processed.

Abstract: The electrical consumption of a cellular mobile telephone is reduced by using fractional-division phase-locked loops receiving a frequency reference from a fairly inaccurate quartz oscillator. Electrical consumption is also reduced by switching the output of the oscillator onto the input of the processing stage when the transmission/reception stage is inactive. The fractional-division phase-locked loops can then be deactivated.
