Most of today's spread-spectrum implementations use a technique called
direct-sequence spread spectrum, which is different from Hedy Lamarr's
invention. Her invention was frequency-hopping spread-spectrum, in which
the sender and receiver agree to switch frequencies at a rapid rate in a
prearranged random or pseudo-random sequence. An eavesdropper who doesn't
know the sequence can't "see" more than a tiny fraction of the
transmission.

Yup, Unless who has a Spectrum Analyzer(HP) connected with High Speed
Computer to record all the channel and re-compile and re-assmble this code,
Good luck...

I belive most big guy have a seed code for key sequence for random number generator to decode this sequence for fraction of time.
