CDMA isn't FH at all.  It is spread spectrum in that it uses the
entire broad spectrum all the time.  All the users share the spectrum
and you xor your psuedo random number with incoming packets and ignore
the ones that don't decode right...  At least that's what I learned
about CDMA phones while I was working at Qualcomm.  I suppose that
Qualcomm employees with double digit badge numbers would be able to
explain what things fairly well :-)
