摘要： A method (100) for generating an ultra-wideband signal is provided. The method comprises the steps of generating (101) at least one ultra-wideband pulse envelope comprising a main pulse and a precursor pulse, the precursor pulse being shorter in length and lower in amplitude compared to the main pulse, and modulating (102) a carrier signal in amplitude such that the envelope corresponds to the at least one ultra-wideband pulse envelope and such that the carrier signal within the main pulse is phase-shifted with respect to the carrier signal within the precursor pulse.

摘要： The invention relates to ultrawide-band pulse generators, particularly for radio communication at frequencies of 2 to 11 GHz. The generator includes an oscillator, providing an output signal at a carrier frequency F
0 , followed by a radiofrequency switching transistor (SW, SW') and a control circuit (CTRL) that controls the gate of the transistor so as to make said transistor conductive for a duration T corresponding to the desired duration of an UWB pulse. The control circuit is arranged so as to consecutively apply, during a single UWB pulse, a first gate voltage V
L that makes the transistor conductive with a first internal resistance value during a first portion of the duration T, then at least one second gate voltage that makes the transistor conductive with a second internal resistance value, different from the first value, during a second portion of the duration T. Said internal resistances cause a different attenuation of the oscillation, during the duration T of the pulse, thus enabling the spectrum of the pulse to be controlled so as to help keep same within the spectrum sizes set by radio communication standards.

摘要： A communication system includes a modulating circuit to increase the amount of information to be transmitted, a transmitting apparatus capable of easily generating a desired waveform even for any very short wavelets, a receiving apparatus capable of easily separating wavelets even if the intervals thereof are narrow. The modulating circuit includes clock generating, transmission signal generating, control signal generating, delay and wavelet generating parts. The clock generating part generates a clock signal at predetermined time interval "Tp". The transmission signal generating part generates a transmission signal at interval "Tp". The control signal generating part outputs a control signal of a predetermined duration based on the clock signal. The delay part generates the control signal as a delay signal that has been delayed by a delay amount based on the transmission signal. The wavelet generating part generates a wavelet at the generation timing of the delay signal.

摘要： The invention relates to a method of generating UWB waveforms each comprising a sequence of elementary pulses, the method comprising steps consisting in: generating at least two pulse signals (E1, E2) each comprising a train of elementary pulses (e1, e2,...) substantially of the same amplitude and of duration corresponding to a setpoint duration, the elementary pulses appearing alternately in the two pulse trains, for each pulse signal, generating an amplitude signal (V1, V2) indicating for each elementary pulse and upon its appearance in the pulse signal an amplitude setpoint (Va1, Va2,...) of the elementary pulse, combining the pulse signals and the amplitude signals to obtain a waveform (s) successively comprising each of the amplified elementary pulses, and alternately positive and negative, the elementary pulses being amplified in accordance with the amplitude setpoint of the elementary pulse, provided by one of the amplitude signals.

Une troisième résistance ajustable (Rcm) est reliée en série avec les résistances (R0, R1), les transistors et la source de courant entre deux bornes d'une source de tension d'alimentation (VDD). Le circuit comprend encore un premier condensateur (C0) relié au noeud de connexion du premier transistor (M0) et de la première résistance (R0) pour fournir un premier signal de sortie (out0), et un second condensateur (C1) relié au noeud de connexion du second transistor (M1) et de la seconde résistance (R1) pour fournir un second signal de sortie (out1). Chaque borne de commande des transistors (M0, M1) reçoit un signal binaire de données respectif (bit0, bit1) pour que le circuit fournisse le premier signal de sortie à impulsions (out0) et le second signal de sortie à impulsions (out1) inversées par rapport aux impulsions du premier signal de sortie, la forme de chaque impulsion dépendant de la charge et de la décharge de chaque condensateur (C0, C1).

摘要： Provided is an ultra-wideband pulse generator using a digital scheme. The ultra-wideband pulse generator and a method for generating an ultra-wideband pulse therein can easily generate various ultra-wideband pulses having a random center frequency and bandwidth according to digital control schemes in a pulse-based ultra-wideband wireless communication system. The ultra-wideband pulse generator includes: a pulse waveform converting block for converting digital pulse waveform information on a desired ultra-wideband pulse into pulse waveform information having positive and negative signs; an unit pulse generating block for multiplying the converted pulse waveform information by a preset short-width pulse and amplifying the resulting pulses according to gain information of the desired ultra-wideband pulse; a pulse waveform arranging block for arranging the amplified pulses at predetermined delayed intervals; and a pulse waveform shaping block for summing the arranged pulses into a single pulse and integrating the single pulse to output the desired ultra-wideband pulse.
