    Abstract

    A 60 GHz wireless Gigabit Ethernet (G.E.) communication system is developed
    at IETR. 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. The realized system covers 2 GHz
    bandwidth. Due to the hardware constraints, a symbol rate at 875 Mbps is
    attained using simple single carrier architecture.

    Abstract

    A 60 GHz wireless Gigabit Ethernet (G.E.) communication system capable of
    near gigabit data rate has been developed at IETR. The realized system covers 2
    GHz available bandwidth. This paper describes the design and realization of the
    overall system including the baseband (BB), intermediate frequency (IF) and
    radiofrequency (RF) blocks. A differential binary shift keying (DBPSK)
    modulation and a differential demodulation are adopted at IF.

    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.

    Abstract

    This paper presents the design and the realization of a hybrid wireless
    Gigabit Ethernet indoor communications system operating at 60 GHz. As the 60
    GHz radio link operates only in a single-room configuration, an additional
    Radio over Fiber (RoF) link is used to ensure the communications within all the
    rooms of a residential environment. The system uses low complexity baseband
    processing modules. A byte synchronization technique is designed to provide a
    high value of the preamble detection probability and a very small value of the
    false detection probability.
