The invention relates to a method for transmitting at least one sequence of Np pulses over Np time windows, each pulse being enclosed within a predetermined time chip Tc. The method according to the invention includes a signal detection step, in the course of which Np detection windows Dj (for j=1 to Np) encompassing predetermined time chips are examined by performing correlations over said detection windows Dj of the received signal with at least a first and a second sinusoidal signal S1 and S2. 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 examine detection windows defined by a signature of a transmitter by using sinusoidal signals, instead of mapping the whole pulse sequence by means of a correlation with expected pulses.
