Abstract
Receiver and reception method of receiving pulsed ultrawideband radio-frequency signals employ an amplification phase, an oscillation phase sensitive to an instability control signal, a shaping phase, and a demodulation phase, and further including an adaptation control step for adapting the receiver or the reception method to the type of signals to be received.
Claims42
A reception device for receiving a pulsed UWB (ultrawideband) radio-frequency signal, the device comprising:
- a super-regenerator oscillator responsive to an instability control signal, the oscillator receiving the pulsed UWB radio-frequency signal;
- shaping means coupled to demodulation means, the shaping means receiving signals output by the oscillator;
- and
- adaptation control means for adapting the reception device to the UWB signal to be received, wherein the adaptation control means are configured to apply the instability control signal adapted to match a sensitivity function of the receiver to the UWB signal which is received.
1 more element
A method of receiving a pulsed UWB (ultrawideband) radio-frequency signal by a receiver, the method comprising successively:
- an oscillation step using an oscillator responsive to an instability control signal and receiving the UWB signal;
- a shaping step;
- and a demodulation step, wherein the oscillation step is a function of an adaptation control step that adapts the reception method to the type of UWB signals to be received by applying the instability control signal adapted to match a sensitivity function of the receiver to the UWB signal that is being received.
