Abstract: PROBLEM TO BE SOLVED: To decode an incident pulse signal of the ultra wideband type through digital processing. SOLUTION: The incident pulse signal of the ultra wideband type conveys digital information encoded by using pulses in a known theoretical shape. A decoding device is equipped with an input means which receives the incident signal and sends a base signal out, a preprocessing means which is so adapted as to receive the base signal and sends out an intermediate signal representing the code of the base signal with respect to a reference, a means which samples an intermediate ISN signal and sends a digital signal out, a synchronizing means, a decoding means, and a digital processing means which is so adapted as to correlate the digital signal with a reference correlation signal corresponding to a theoretical base signal arising from the reception of the theoretical pulses having the known theoretical shape.

Abstract: PROBLEM TO BE SOLVED: To monitor transmission power of a remote terminal, e.g. a cellular mobile telephone, by a method for optimizing the efficiency without sacrifice of the quality of a service being transmitted. SOLUTION: Transmission power is regulated depending on a power information item being received by a telephone. The telephone is provided with a variable gain amplifying means covering the power range and the values of the gain and supply voltage of the amplifying means are regulated depending on the power information item. The amplifying means comprises at least two separately selectable power amplifiers which can cover the entire power range together and have a specified operating zone and a common operating zone, respectively.

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 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.
