Abstract: The transmission power control method has the transmission power adjusted as a function of the power information received. The transmitter has two power amplifiers (PA1,PA2) which are individually selectable together covering the total power plane. Each amplifier covers a different power zone, and is selected as a function of transmission efficiency. There is a transmission interrupt criteria, after which the amplifiers are reset.

Abstract: Ces procédés de démodulation souple de données modulées suivant une modulation d'amplitude en quadrature s'appliquent dans un système de communication mettant en oeuvre une technique d'accès multiple à répartition par codes ou CDMA et un multiplexage par division de fréquences orthogonales ou OFDM, utilisant des codes d'étalement binaires ou non binaires. Ils comportent des étapes (340) consistant à déterminer un logarithme du rapport de vraisemblance ayant une expression particulière.

Abstract: The procedure for estimation of the pulse response of an information transmission channel comprises an evaluation of the useful number (N2) of coefficients of the pulse response of the channel as a function of the real characteristics of the transmission channel. This includes the evaluation of a time spreading parameter (ds) for the transmission channel. The procedure for estimation of the pulse response of an information transmission channel comprises an evaluation of the useful number (N2) of coefficients of the pulse response of the channel as a function of the real characteristics of the transmission channel. A first estimation (30) of the pulse response is effected by using a predetermined maximum value for the number of coefficients of this pulse response. The evaluation of the useful number of coefficients comprises the evaluation of a time spreading parameter (ds) for the transmission channel, and the determination of a final estimation (H2) of the pulse response of the channel taking account of the useful number of coefficients.

Abstract: A layered capacitor device with high capacitance per unit area is realised by alternating in the vertical direction first layers (FL1, FL2, FL3, FL4, FL5) and second layers (SL1, SL2, SL3, SL4). A first layer (FL2) consists of horizontally alternating electrically conducting tracks (T2,2; T2,3) and electrically insulating tracks, whereas a second layer consists of electrically insulating material, e.g. an oxide. In this way top-bottom capacitors (CTB) and side-wall capacitors (CSW) are constituted that are parallel coupled to form the layered capacitor device. In a preferred embodiment of the invention, this parallel coupling is realised by conductively interconnecting diagonally neighbouring electrically conducting tracks (T1,2; T2,3).

Abstract: The present invention relates to a frequency synthesiser for generating an output signal (So) the frequency of which has a non-integer, fractional relationship of value Nn/Nd, where Nn and Nd are integer numbers, with respect to a frequency (fr) of an input signal (Sr). The synthesiser is characterised in that it comprises means (20) for multiplying by M, where M is an integer number, the frequency of said input signal in order to produce a high frequency intermediate signal (Si), and means (21) for dividing the frequency of this intermediate signal by (MxNd)/Nn in order to generate said output signal (So).

Abstract: The method involves forming an estimate of the radio channel impulse response at a given instant and then forming the time derivative of this estimate. A relationship is determined that involves a denominator taking into account the energy of the estimated impulse response and a numerator taking into account the energy of the estimated time derivative of the impulse response.

Abstract: An interface arrangement including the cascade connection of a differential pre-amplifier (HPA1, HPA2) and a comparator (DA), and generally known as fast Low Voltage Differential Signal LVDS circuit for interfacing electronic chips. The current standards for such a LVDS circuit specify a minimum switching threshold voltage for the small differential input signal, while the common mode input signal varies over a very large range, both at a very high frequency. This is achieved owing to the fact that the differential pre-amplifier comprises a first (HPA1) and a second (HPA2) half pre-amplifier, each receiving the arrangement inputs (INN, INP) in an opposite way. Each half pre-amplifier (HPA1/HPA2) having first input inverter means (NN1, PN1) coupling an input (INN/INP) to an output (OUT1/OUT2) thereof, and second input inverter means (NP1, PM1, PM2; PP1, NM1, NM2) coupling the other input (INP/INN) to the output via current mirror means (PM1, PM2; NM1, NM2). The output current of the second input inverter means is thereby inverted with respect to the output current of the first input inverter means. To obtain a controlled gain, the half pre-amplifier further includes a short-circuited inverter.
