摘要：
A broadband 64kbit/s DS-CDMA overlay in the same frequency space as a GSM signal has been implemented experimentally in a fading environment. With a single CDMA user, error-free operation of both systems was demonstrated over a 39 and 58dB dynamic range for the uplink and the downlink, respectively. The work utilised a novel CDMA receiver architecture that enabled a 30dB digital notch filter to be applied at RF. This represents the first experimental demonstration of a true GSM network overlay in a realistic radio channel.
