Patent ID: 7551891

Claim:
A method for receiving data in an Ultra-Wide Band (UWB) telecommunication system including at least one transmitter and one receiver, said transmitter being configured to transmit a UWB 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, said method comprising: performing a first correlation and a second correlation over Np detection windows encompassing time chips defined by chip numbers of a signal representative of a received UWB signal with a first sinusoidal signal and a second sinusoidal signal, respectively, wherein the first sinusoidal signal and the second sinusoidal signal are in phase quadrature with respect to each other, and each correlation includes multiplication and integration; producing a first correlation result and a second correlation result from said performing step; combining said first correlation result and said second correlation result into a detection value; comparing said detection value to a predetermined threshold value to obtain a comparison result; and determining whether an expected pulse sequence is detected based on said comparison result.
