| 1. A method for receiving data in a telecommunication system including at least one transmitter and one receiver, the method
comprising:
transmitting from said transmitter a signal formed by at least one sequence of Np pulses over Np time windows where Np is
a predetermined integer number, each pulse being enclosed within a time chip whose position within its relevant time window
is defined by a chip number;
characterizing said signal, in said receiver, by examining Np detection windows encompassing the time chips defined by the
chip numbers in search of an expected pulse sequence, and thus only scanning selected portions and not all portions of said
expected pulse sequence, by performing at least a first and a second correlation over said detection windows of a signal representative
of the received signal with at least a first and a second sinusoidal signal, respectively, said first and second sinusoidal
signals are in phase quadrature with respect to each other; and
producing first and second correlation values, based on said first and second correlations, representative of the amplitude
and phase of a received pulse sequence.
