Abstract:
1. A method of sending ultra-wide band signals via a plurality of sending antennas comprising a phase for sending training sequences followed by a phase for sending data sequences, wherein each antenna of the plurality of sending antennas sends a waveform using a Hermite pulse that is unique and orthogonal to the waveforms sent by the other antennas, whereby training sequences sent by an antenna of the plurality of antennas use a given Hermite pulse and data sequences sent by the antenna use the given Hermite pulse wherein, in the phase for sending training sequences, on each antenna of the plurality of sending antennas, a term-by-term multiplication is performed of a sequence of training symbols (S Nseq , . . . , S 1 ) with a sequence of parity codes (c Nseq (i) , . . . , c 1 (i) ) where each parity code satisfies the following relation: where N
