Abstract

This paper presents the study and the realization of a hybrid 60 GHz wireless communications system. As the 60 GHz radio link operates only in a single-room configuration, an additional Radio over Fibre (RoF) link is used to ensure the communications in all the rooms of a residential environment. A single carrier architecture is adopted. The system uses low complexity baseband processing modules. A byte/frame synchronization technique is designed to provide a high value of the preamble detection probability and a very small value of the false alarm probability. Conventional RS (255, 239) encoder and decoder are used to correct errors in the transmission channel. Results of Bit Error Rate (BER) measurements are presented for various antennas configurations.
