Until I've actually read the paper, ask yourself how our GPS receivers is able to track signals below their internal noise. There are a number of tricky aspects involved in doing that and I beleive the paper goes into those. I have it in print here and will read it as I come back home. Cheers, Magnus Weekend reading for me too :) But GPS uses highly correlated 'noise' which allows the payload data to be below the noise floor through simple correlation since the noise is expected to be random. Just wondering about the numbers, -200dBc/Hz is 10 Billion times smaller than the carrier, and that's in terms of voltage leves - power is that number squared... bye, Said ************************************** See what's free at http://www.aol.com. _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
