Abstract: A method for the detection of a pulse of a signal received by a receiver device, the received signal corresponding to data emitted with a predetermined period Tc, each piece of data being encoded by a presence or an absence of a pulse. The method includes: temporally offsetting of the received signal according to a predetermined number Ns of delays corresponding to different multiples of Tc, so as to generate Ns delayed signals; correlating, at a time that is a candidate for the detection of a pulse, the received signal with each of the delayed signals, in so as to obtain Ns correlation values associated with the candidate time; calculating a maximum correlation value among the Ns correlation values associated with the candidate time; anddetecting a pulse of the received signal according to the maximum correlation value.

Abstract: A method for transmitting a bit sequence to be transmitted at a frequency fb. A set of codes is determined in advance, wherein each code is associated with a possible value from a block of Nb bits, and each code includes an ordered set of Ns binary symbols intended to be transmitted at a frequency fs. The method includes splitting the bit sequence into N blocks of Nb bits, the frequency fs and the numbers N and Nb being selected such that Ns×fb=N×Nb×fs, associating a code with each of the N blocks according to the value from the blocks, interleaving the binary symbols of the N codes respectively corresponding to the N blocks of bits to be transmitted, the interleaved binary symbols being transmitted at a frequency fc such that N×fs=fc.
