Devices and methods for transmitting and receiving, signal transmitter-receiver

Abstract

The invention relates to a device for transmitting an ultra-wideband-type signal, the signal including, one after the other temporally, a synchronization header and a data payload field. The transmission device includes a first generator to generate first synchronization header symbols and a third generator to generate third data payload symbols. The transmission device further includes a time sequencing device for sequencing the first and third symbols in a sequence of symbols, successively including the first symbols in the synchronization header and the third symbols in the data payload field. The transmission device further includes at least one antenna, capable of transmitting the signal including the sequence. The transmission device additionally includes a fourth generator to generate at least one fourth secret symbol, the time sequencing device being configured to insert the at least one fourth secret symbol into the sequence of symbols.
