摘要： A pulsed multi-channel UWB receiver. The receiver includes a first stage translating a received signal into baseband or at an intermediate frequency, a second stage carrying out quadrature mixing on the in-phase and quadrature channels of the first stage, a third stage carrying out an integration on a time window of the signals from the second stage, and a fourth stage carrying out a combination of the integration results from the third stage to provide the real part and the imaginary part of the modulation symbol. The receiver is configurable according to the receiving channel and processing type selected.

摘要： An impulse UWB signal multi-antenna receiver with an RF front-end shared between the various antennas. The receiver includes a code multiplexing stage upstream of the RF front-end, and a code demultiplexing stage downstream of this front-end. The codes used for multiplexing and demultiplexing are orthogonal codes with timing a sub-multiple of the chip timing of the code used at transmission for modulation of the impulse UWB signal.

摘要： A UWB impulse receiver including an RF stage followed by a baseband processing stage. The baseband processing stage includes a Rake filter including a plurality of time fingers, each finger including an integrator of the baseband signal during an acquisition window, a control module, and a detection module estimating the received symbols from the integration results. During a synchronization phase, the control module drives respective positions of the acquisition windows associated with the different fingers, to scan at a reception interval, the RF stage only operating, in a course of the synchronization phase, during the plurality of acquisition windows.

摘要： Device for adjusting the locking of an injection locked frequency multiplier, including: a first input receiving a first signal of frequency f1, and a second input receiving a second signal of frequency f2 outputted by the frequency multiplier; a sub-sampler of the second signal; a control circuit configured for: receiving a third signal corresponding to the second signal sub-sampled by the first signal or by another multiple signal of frequency of f1, then carrying out a high-pass or band-pass filtering of the third signal; determining that the frequency multiplier is locked on a multiple of f1 when the signal obtained after filtering is substantially zero, then outputting a signal the value of which is representative of the locking or not of the frequency multiplier.

摘要： An ultra-wideband pulse generator, for radio communication at frequencies of 2 to 11 GHz comprises an oscillator providing an output signal at carrier frequency F0 followed by a radiofrequency switching transistor and a control circuit controlling the gate of the transistor to turn it on for duration T corresponding to the desired duration of a UWB pulse. The control circuit is arranged to successively apply, during the same UWB pulse, a first gate voltage turning the transistor on with first internal resistance value for a first part of duration T, a second gate voltage that turns the transistor on with second internal resistance value, different from the first, for a second part of duration T. These internal resistances cause the oscillation to be attenuated differently for duration T of the pulse, allowing the spectrum of the pulse to maintain it within the spectral templates imposed by the radio communication standards.
