    摘要: The present invention relates to a method for transmitting data in the form of at least one pulse sequence Tsgk (for k=1 to K). The method according to the invention includes at least one symbol decoding step in the course of which at least one modulation value Pwk representative of an amount of power carried by each pulse sequence Tsgk is computed and compared to at least one predetermined threshold value Thvk, which will be computed beforehand by equating a first and a second probability density function representing a likelihood for the transmitted signal to carry a first symbol and a likelihood for the transmitted signal to carry a second symbol, respectively. The method according to the invention enables to limit the processing time and power needed for performing the demodulation of a power-modulated UWB signal.

    摘要: The present invention relates to a method for transmitting data by means of at least one pulse sequence carried by a radio signal, in the course of which a power value representative of an amount of power carried by said pulse sequence is computed. The method according to the invention provides estimated values of noise affecting the radio transmission and of an amount of power which would be carried by each pulse sequence in the absence of noise, respectively, prior to the determination of a threshold value to which the power value is to be compared. The knowledge of such estimated values enables to compute a threshold value adapted to the communication conditions affecting any given pulse sequence, and hence to perform an optimal demodulation of any power-modulated UWB signal.

The method according to the invention includes at least one symbol encoding step, in the course of which each pulse pj (for j=1 to Ns) of an ith pulse sequence Tsg is multiplied by a value Vi representative of a symbol to be carried by said sequence.
