Patent ID: 7508879

Claim:
A telecommunication system comprising: at least one transmitter and one receiver, respectively configured to transmit and receive a signal formed by at least one pulse sequence modulated by symbol encoding units included in the transmitter; the symbol encoding units including, a plurality of signal encoders connected to a plurality of antennas, and each signal encoder comprising: a pulse generating unit configured to deliver a basic pulse sequence, a first energy splitting unit configured to split said basic pulse sequence into at least two split sub-sequences having respective different frequency sub-bands, a signal modulating unit configured to apply to the split sub-sequence obtained from the splitting of the basic pulse sequence a tunable coefficient representative of a symbol to be carried by said split sub-sequence, and a combination unit configured to combine the split sub-sequences delivered by the signal modulating units into a signal to be transmitted by one of the plurality of antennas to which one of the plurality of signal encoders is connected; wherein the antenna included in said transmitter is connected, via a switch unit, to a signal encoder and to a signal decoder, the combination unit included in said signal encoder and a second energy splitting unit included in a signal decoder constituted by a same reversible frequency multiplexing module.
