ABSTRACT:
The present invention relates to a method for transmitting data in the form of at least one sequence of Np pulses over Np time windows Tf, each pulse being enclosed within a time chip Tc whose position within its relevant time window is defined by a chip number. The method according to the invention, includes at least one signal detection step, in the course of which Np detection windows Dj (for j=1 to Np) encompassing the time chips defined by the chip numbers are to be examined in search of an expected pulse sequence. The method according to the invention enables to limit the processing time and power needed for carrying out the detection step, which only requires to scan detection windows defined by the signature of a transmitter, instead of mapping the whole pulse sequence.
