Information Spatial focusing scheme for UWB Wireless Communications in Smart Environments
Résumé
This letter presents an information spatial focusing method for future Smart Environments using UWB Wireless communications. This method allows to send high data rate information at predetermined specific spatial positions without localizing users, thereby protecting their privacy. The proposed approach is a combination of simplified Ultra Wide Band (UWB) Beamforming and signal processing. Compared to classical UWB Beamforming, the proposed method exhibits greater information focusing capabilities by increasing greatly the peak-to-floor ratio between main and side beams.
