Re: UWB-Receiver
Hello UWB-Man,
i think "Direct Spread Spectrum" and "Frequency Hopping Spread Spectrum" are just the beginning of what UWB will bring.
I would say, mainly real UWB applications (500MHz to 2 GHz to ...) will use "monocycle time hopping spread spectrum" and familiar techniques.
I dont know the used receiver topologies in great detail, but I think it is based on correlation and matched filters.
If we think of an 24GHz +- 2 GHz UWB signal. Is it possible to downconvert to DC...2 GHz without loosing the information ? Probably, yes. Anyway, there is still the question how to process this DC...2GHz signal. Could we use conventional receivers ? How do we know, which frequency band has to be analysed at a specific time t0 ?
Where can I get information on real UWB-receivers ?
Thank you very much.
