A telecommunication system including a receiver to receive a signal including a sequence of Np pulses, each pulse included in a separate time window, and each pulse enclosed within a time chip whose position within the corresponding time window is defined by a chip number that is included in a known signature; and a detector configured to detect Np pulses in each of the separate time windows by using Np detection windows, a location of the detection windows defined by the known signature, the detection windows being shorter than the separate time windows, and longer than the time chip duration of the time chips, to search an expected pulse sequence.

Method for detecting UWB pulse sequences and detection means suitable for this purpose

A system to transmit data in the form of at least one pulse sequence modulated by symbol encoding units. The symbol encoding units include a plurality of signal encoders (ENCi) connected to a plurality of antennas, pulse generating units (PGi) for delivering a basic pulse sequence (PSQi), first energy splitting units (ENSPi) for splitting basic pulse sequence into sub-sequences (Psqi-PsqiK), signal modulating units (SGM-SGMK) for applying to the sub-sequence a tunable coefficient, and combination units (CMBMi) for combining the sub-sequences (Tsgi-TsgiK) into a signal (Tsgi) to be transmitted by the antenna (ANTi) to which the encoder (ENCi) is connected. Each signal encoder (ENCi) is linked to a single antenna (ANTi).
