摘要
The paper presents the system design concept for a mobile broadband communications system at 60 GHz. A dense WDM system is used for the optical backbone employing novel add/drop multiplexers. For simplicity, there is no signal processing and frequency generation at the base station and a master oscillator signal are used for millimetric carrier generation. The master oscillator signal is modulated onto the optical carriers by a novel concept of simultaneous external modulation, simplifying system design significantly. Transmission experiments over a complete downlink path using uncoded 2-FSK have been carried out and a BER of 10(-9) at 50 MBit/s has been obtained. Furthermore, 512-carrier DQPSK-OFDM transmission at 45.8 MBit/s using 35 MHz bandwidth at 60 GHz has been demonstrated.
