Abstract
A pulse train with known values and a known length contained in a signal is identified. The mathematical sign of the phase difference between successive samples of the signal is used to assess whether the transmitted pulse is a 1 or a 0, and with the sum of the pulses being determined in a window which is proportional to the length of the pulse train. The pulse train is considered as being identified at the time when the sum of the pulses in the search window exceeds a given threshold value.
