The paper presents the system designconcept for a mobile broadband communications systemat 60 GHz. A dense WDM system is used for the opticalbackbone employing novel add/drop multiplexers. Forsimplicity, there is no signal processing andfrequency generation at the base station and a masteroscillator signal are used for millimetric carriergeneration. The master oscillator signal is modulatedonto the optical carriers by a novel concept ofsimultaneous external modulation, simplifying systemdesign significantly. Transmission experiments over acomplete downlink path using uncoded 2-FSK have beencarried out and a BER of 10-9at 50 MBit/s hasbeen obtained. Furthermore, 512-carrier DQPSK-OFDMtransmission at 45.8 MBit/s using 35 MHz bandwidth at60 GHz has been demonstrated. [ABSTRACT FROM AUTHOR] |
