Patent ID: 7684500

Claim:
A method for transmitting data in a telecommunication system including at least one transmitter and one receiver, comprising: transmitting, from said transmitter, a signal formed by at least one reference sequence including a predetermined number of pulses dispatched over a same predetermined number of time windows, each pulse of the reference sequence being enclosed within a time chip whose position within its relevant time window is defined by a chip number; receiving, at the receiver, the signal transmitted by the transmitter; computing, at the receiver, at least one detection value representative of an amount of power carried by the received signal by integrating the received signal over a time duration which is tunable; and comparing, at the receiver, the computed detection value to at least one predetermined threshold value, wherein the detection value is computed by selecting an initial number of time windows for constituting an initial detection pattern and performing an initial cycle of successive integrations of the received signal over successive time-shifted detection patterns, each integration being followed by a comparison of the resulting detection value with the predetermined threshold value, said initial cycle being carried out until a detection value is found higher than said predetermined threshold value, or until all possible beginnings of a transmitted pulse sequence will have been covered by each first window of each time-shifted detection pattern, in which case the number of the time windows to be included in the detection pattern is increased and a new cycle of successive integrations is performed.
