Patent ID: 7839962

Claim:
A method for synchronising a signal frame transmitted by a transmitter of a telecommunication system to a receiver adapted to synchronise said signal frame from a synchronisation sequence included in said signal frame, the method comprising: a synchronisation sequence generation step executed by the transmitter in which the synchronisation sequence is formed by a concatenation of first and second bursts of L complementary sequences, said first burst of L sequences being obtained by a concatenation of L times a first N pulses complementary sequence of a pair of complementary sequences, said second burst of L sequences being obtained by a concatenation of L times a second N pulses complementary sequence of said pair of complementary sequences, and a sequence weighting step executed by the transmitter in which pulses of each complementary sequence of rank q of the first burst of L sequences are multiplied by a component of rank q of an L components long weighting code belonging to a set of I weighting codes known by the receiver beforehand, and pulses of each complementary sequence of rank q of the second burst of L sequences are multiplied by the same component of rank q of said weighting code.
