ABSTRACT:
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.
