Abstract: PROBLEM TO BE SOLVED: To optimize the efficiency of transmission power without affecting the quality of a service by controlling the power of a remote terminal equipment or particularly a cellular mobile telephone. SOLUTION: The cellular mobile telephone comprises at least two power amplifiers each having a common operating region. If one of the amplifiers must be disconnected, the best time of switching is specified based on a predetermined transmission interrupting reference. The presently selected amplifier is used and its power regulation is continued until the switching time arrives. When the time arrives, the transmission is once interrupted, and then another amplifier is switched on.

Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of a digital information transmitting/receiving device, especially a cellular mobile telephone set. SOLUTION: The process consists of a fractional-dividing phase-synchronous loop for receiving a basic signal (SBA) from an oscillator of low accuracy, and outputs a clock signal (SH) of high accuracy when a transmitting/receiving step is in an active state, and changes over the output of the oscillator to an input part of a processing step when the transmitting/receiving step is in an inactive step, thereby achieving reduction in the power consumption.

Abstract: The method comprises an interference reduction mode (ADIRM) for reducing interferences between a wide band device and a narrow band device; said method is performed within said wide band device and includes the steps of detecting (130) an emission from and/or a reception performed by said narrow band device, determining (131) from said detection step a group of at least one sub-carrier having frequencies interfering with the narrow band device, frequency shifting (132) at least a part of frequency band of said wide band device including said group of at least one interfering sub-carriers with a chosen frequency shift such that at least a part of frequency band of said narrow band device is excluded from said frequency band of said wide band device.

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.

Abstract: The analogue signal analogue to digital conversion method has a mobile telephone reception stage with a delta sigma parameterable converter (CAN). During transmission converter parameters are adjusted as a function of the transmission index of digital conditions and real reception conditions.

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: The Rake receiver uses a delayed version of the received sequence and a delayed version of scrambling code. The flexible hardware structure of the time-aligning and descrambling unit (DSU) comprises at least two delay chains (DCH1, DCH2A) and one multiplier (MTM). By controlling two multiplexers (MUX1, MUX2), the delayed versions of the received sequence can be multiplied with an arbitrary scrambling code having an arbitrary phase. During one chip period, for each path to be processed, one multiplication is performed.
