A focusing technique based on a data spatial diversity at millimetre-wave frequency

This paper presents a new topology of data coding and data broadcasting exclusively sent to a specific location area. The proposed technique exploits specifically different received signals to focus energy and to rebuild information intelligibly only for a chosen position. By this way, the receiver coordinates become its own “key” to decode the transmitted data. The overall topology uses multiple emitters and one receiver which reads clearly the transmitted information only at precise coordinates. This “Dedicated Transmission” technique enables a spatial multiplexing and has been validated experimentally using Ultra Wide Band (UWB) signals around 4.5 GHz and in the millimeter frequency range.
