Système de Communications Sans Fil Très Haut Débit à 60 GHz

This paper presents the study and the realization at IETR of a high data rate 60 GHz wireless communications system. The system uses a simple single carrier architecture. The receiver architecture is based on a differential demodulation which minimizes the intersymbol interference (ISI) effect and a signal processing unit composed of a joint frame and byte synchronization block and a conventional RS (255, 239) decoder. The byte synchronization technique provides a high preamble detection probability and a very small value of the false detection probability. First measurement results show a good communication link quality in line of sight environments with directional antennas.
