The disclosure relates to a method for generating UWB waveforms, each comprising a sequence of pulses, the method comprising: generating consecutive elementary pulses having durations corresponding to setpoint durations and a constant amplitude, amplifying each elementary pulse separately as a function of a respective setpoint amplitude, and combining the amplified elementary pulses to obtain a waveform successively comprising each of the amplified alternately positive and negative, elementary pulses.

Method and device for generating ultra wide band pulses

There is provided a detector for extracting binary data frequency-modulated on a carrier signal. An axes generator produces M pairs of logic signals, the logic signals of the same pair being in quadrature. The decoder includes M asynchronous logic zero-crossing detectors producing first pulses and second pulses. An up-counter/down-counter has first, second and third values, and when it has the second value, passing to the first value during a first pulse, and passing to the third value during a second pulse, and a binary decoder generates binary data whose state is not modified when the up-counter/down-counter passes from the first value to the second value or from the third value to the second value. No external time base is required and the decoder has a reduced bit error ratio.
