Abstract
A method for decoding a pulsed signal coded by phase jumps, in which each bit is coded by N pulses of the coded signal and a change of the value of a bit in relation to the previous bit is coded by an inversion of the coded signal phase. The method has steps of sampling the coded signal by a pulsed strobe of the same frequency as the coded signal, with a sampling window the duration of which is less than the duration of one pulse of the coded signal. For each group of N pulses of the coded signal, the number of sampled pulses resulting from the sampling of the coded signal is counted, and then the value of the bit coded by the group of N pulses is deduced from it.
